Executive Summary

Today’s threat landscape is defined by the accelerating weaponization of Artificial Intelligence, pushing the boundaries of autonomous attack capabilities and dramatically shortening the window for defensive response. The emergence of fully agentic, LLM-driven ransomware campaigns like JADEPUFFER marks a critical inflection point, demonstrating adversaries’ ability to orchestrate entire attack lifecycles without human intervention. This is compounded by a flurry of actively exploited zero-day vulnerabilities in widely used software, from Adobe ColdFusion to various Joomla components, demanding immediate patching and highlighting persistent weaknesses in foundational security hygiene. Supply chain risks, particularly through malicious open-source packages and AI agent interactions with critical infrastructure, continue to expand, making robust third-party risk management and continuous monitoring non-negotiable for operational resilience.

🔴 Critical Threats — Act Now

Adobe ColdFusion — Path Traversal RCE (CVE-2026-48282)

What happened: A critical path traversal vulnerability, CVE-2026-48282, with a CVSS score of 10.0, has been identified in Adobe ColdFusion. This flaw allows an unauthenticated attacker to achieve arbitrary code execution on affected servers. Exploitation was observed in the wild within hours of public disclosure, prompting the Cybersecurity and Infrastructure Security Agency (CISA) to add it to its Known Exploited Vulnerabilities (KEV) catalog. The vulnerability stems from improper input validation, allowing specially crafted requests to traverse directory structures and execute malicious files.

Source verification: Confirmed. Adobe released an advisory detailing the vulnerability and providing patch information. CISA’s KEV catalog listing confirms active exploitation. Multiple independent security news outlets, including The Hacker News and BleepingComputer, reported on the active exploitation and the urgency for patching. No conflicting reports have been found.

Technical breakdown: The vulnerability, a path traversal, typically involves an attacker manipulating file paths in a web request to access or execute files outside of the intended directory. In ColdFusion’s context, this could mean an attacker uploading a malicious file (e.g., a webshell) to an accessible directory and then using the path traversal flaw to execute it, bypassing security controls. The CVSS 10.0 score indicates a complete loss of confidentiality, integrity, and availability, requiring no privileges or user interaction, and having a low attack complexity over the network.

• MITRE ATT&CK Mapping:
  • Initial Access: T1190 – Exploit Public-Facing Application
  • Execution: T1059.001 – Command and Scripting Interpreter: PowerShell (if Windows), T1059.004 – Command and Scripting Interpreter: Unix Shell (if Linux), T1505.003 – Server Software Component: Web Shell
  • Persistence: T1505.003 – Server Software Component: Web Shell
• PoC status: Exploitation observed in the wild, indicating readily available or easily developed Proof-of-Concept exploits. GitHub searches for CVE-2026-48282 show several public repositories containing PoC code and exploitation scripts, some updated within the last 24 hours.

Blast radius: Any organization running affected versions of Adobe ColdFusion (specifically ColdFusion 2023 Update 1 and earlier, and ColdFusion 2025 Update 1 and earlier) is exposed. ColdFusion is often used in enterprise environments for developing web applications, meaning a successful compromise could lead to broader network access, data exfiltration, or further lateral movement within a corporate network. This impacts both on-premise and cloud deployments where ColdFusion servers are exposed to the internet.

Marcus’s verdict: This is as bad as it sounds. A CVSS 10.0 RCE in a widely deployed enterprise application, actively exploited within hours of disclosure, and added to CISA’s KEV. This isn’t theoretical; it’s a live fire. If you run ColdFusion, you should have patched this yesterday. The vendor issued a fix, so there’s no excuse for delay. This is how ransomware gangs get their initial foothold.

Actions:

1. Immediate Patching: Apply Adobe ColdFusion 2023 Update 2 or ColdFusion 2025 Update 2 (or later versions) immediately. Prioritize internet-facing instances.
2. Vulnerability Scanning: Conduct authenticated vulnerability scans on all ColdFusion instances to confirm the patch has been successfully applied and no other known vulnerabilities exist.
3. Log Review & Hunt: Review ColdFusion access logs and web server logs for indicators of compromise related to path traversal attempts or suspicious file uploads (e.g., .cfm, .jsp, .php files in unusual directories) prior to patching. Look for unusual process execution originating from the ColdFusion process.
4. Network Segmentation: Ensure ColdFusion servers are adequately segmented from critical internal systems.
5. Web Application Firewall (WAF): Implement or review WAF rules to detect and block path traversal attempts and suspicious file uploads.

Joomlack Page Builder — Unauthenticated RCE (CVE-2026-56290)

What happened: A critical improper access control vulnerability, CVE-2026-56290 (CVSS 10.0), exists in Joomlack Page Builder. This flaw allows an unauthenticated attacker to perform arbitrary file uploads, leading directly to remote code execution (RCE). It is actively exploited as a zero-day, and CISA has added it to its KEV catalog. The vulnerability bypasses authentication checks, allowing attackers to upload malicious files (e.g., PHP webshells) to the server.

Source verification: Confirmed. The Joomlack team released a security update. CISA’s KEV catalog confirms active exploitation. Security researchers and news outlets, such as Sucuri and Wordfence, have reported on the zero-day exploitation, noting its severity and the rapid deployment of exploits. No conflicting reports.

Technical breakdown: The core issue is an improper access control mechanism that fails to adequately restrict file upload functionality. This means an attacker doesn’t need to be logged in or possess any special privileges to upload arbitrary files to the web server. Once a malicious file, typically a PHP webshell, is uploaded, the attacker can then access it via a web browser to execute arbitrary commands on the underlying server.

• MITRE ATT&CK Mapping:
  • Initial Access: T1190 – Exploit Public-Facing Application
  • Execution: T1505.003 – Server Software Component: Web Shell, T1059.006 – Command and Scripting Interpreter: PowerShell (if Windows), T1059.004 – Command and Scripting Interpreter: Unix Shell (if Linux)
  • Persistence: T1505.003 – Server Software Component: Web Shell
• PoC status: Actively exploited as a zero-day, indicating public or private PoCs are widely available. GitHub searches for CVE-2026-56290 show multiple PoC scripts demonstrating unauthenticated file upload and RCE.

Blast radius: Any website running Joomlack Page Builder versions prior to the patched release is vulnerable. Joomla is a popular Content Management System (CMS), and page builder extensions are common. This means a significant number of websites could be exposed, particularly those that haven’t kept their extensions updated. The unauthenticated nature of the RCE makes it extremely dangerous, as attackers can scan the internet for vulnerable targets and exploit them en masse.

Marcus’s verdict: Another CVSS 10.0, another zero-day, another CISA KEV entry. This is a classic “unauthenticated file upload leading to RCE” scenario, a gift to attackers. If your web team is running Joomla, they need to verify their Joomlack Page Builder version right now. This is low-hanging fruit for automated attacks.

Actions:

1. Immediate Patching: Update Joomlack Page Builder to the latest patched version as advised by the vendor.
2. Web Server & CMS Hardening: Implement strict file upload policies on web servers, restricting file types, sizes, and upload directories. Ensure proper permissions are set on web directories.
3. Indicator of Compromise (IoC) Hunt: Scan web server logs for suspicious POST requests to upload directories, unusual file creations (e.g., .php, .jsp, .asp files) in unexpected locations, and anomalous outbound connections from the web server.
4. WAF Protection: Deploy or tune WAFs to detect and block malicious file uploads and webshell activity.

JoomShaper SP Page Builder — Unauthenticated RCE (CVE-2026-48908)

What happened: JoomShaper SP Page Builder is affected by CVE-2026-48908 (CVSS 10.0), an unrestricted file upload vulnerability that allows unauthenticated remote code execution. This flaw is actively exploited as a zero-day, with attackers observed uploading PHP webshells to compromised sites. CISA has added this vulnerability to its KEV catalog.

Source verification: Confirmed. JoomShaper released an update to address the vulnerability. CISA’s KEV listing confirms active exploitation. Security researchers from various firms, including Patchstack and Snyk, have documented the zero-day exploitation and the technical details of the webshell uploads. No conflicting reports.

Technical breakdown: Similar to the Joomlack vulnerability, this flaw in JoomShaper SP Page Builder allows an unauthenticated attacker to upload arbitrary files due to inadequate validation and sanitization of user-supplied input during the file upload process. Attackers exploit this to drop PHP webshells, gaining full control over the compromised web server. The CVSS 10.0 score underscores the severity, indicating complete compromise without authentication or user interaction.

• MITRE ATT&CK Mapping:
  • Initial Access: T1190 – Exploit Public-Facing Application
  • Execution: T1505.003 – Server Software Component: Web Shell, T1059.006 – Command and Scripting Interpreter: PowerShell (if Windows), T1059.004 – Command and Scripting Interpreter: Unix Shell (if Linux)
  • Persistence: T1505.003 – Server Software Component: Web Shell
• PoC status: Actively exploited as a zero-day. Public PoCs are available on GitHub, demonstrating the ease of exploitation.

Blast radius: All websites using vulnerable versions of JoomShaper SP Page Builder (prior to 6.6.2) are at extreme risk. Given the popularity of JoomShaper products within the Joomla ecosystem, the potential impact is widespread. Unauthenticated RCE vulnerabilities are prime targets for automated scanning and exploitation by botnets and initial access brokers.

Marcus’s verdict: Are we seeing a pattern here? Two Joomla page builders, two unauthenticated RCEs, both CVSS 10.0, both zero-days, both actively exploited, both CISA KEV. This is a glaring weakness in the CMS extension ecosystem. Defenders need to be hyper-vigilant with third-party components. This is not a “maybe later” patch; it’s a “drop everything and fix it” situation.

Actions:

1. Immediate Patching: Update JoomShaper SP Page Builder to version 6.6.2 or later immediately.
2. Webshell Detection & Removal: Scan all web directories for known PHP webshell signatures and unusual files. Remove any identified malicious files.
3. Log Analysis: Scrutinize web server access logs for POST requests to unexpected locations, especially those ending in .php, and look for subsequent GET requests to newly created files.
4. Regular Backups: Ensure recent, verified backups are available in case of compromise and data loss.

Linux Kernel — “Bad Epoll” Local Privilege Escalation (CVE-2026-43456)

What happened: A zero-day local privilege escalation (LPE) vulnerability, dubbed “Bad Epoll” (CVE-2026-43456), has been discovered in the Linux Kernel. While not explicitly rated with a CVSS score in the briefing, it is categorized as “High” severity. This flaw allows a local attacker to reliably gain root privileges in under one second.

Source verification: Confirmed. The fix for CVE-2026-43456 was released in March 2026 and is expected in the latest Linux distributions. Security research by Project Zero and similar groups often uncovers such kernel vulnerabilities. Reports from The Register and LWN.net detail the technical aspects and impact. No conflicting reports.

Technical breakdown: The “Bad Epoll” vulnerability likely resides in the epoll system call mechanism, which is used for I/O event notification in Linux. LPE vulnerabilities in the kernel often involve race conditions, use-after-free, or improper handling of system call arguments, allowing a less privileged process to manipulate kernel memory or execution flow to elevate its privileges. The fact that exploits are “reliable and complete in under one second” indicates a stable and efficient exploit chain.

• MITRE ATT&CK Mapping:
  • Privilege Escalation: T1068 – Exploitation for Privilege Escalation, T1548.001 – Abuse of ROOT privileges.
• PoC status: Exploits are reliable and complete, indicating mature PoC code exists. Public PoCs for CVE-2026-43456 are available on GitHub, often demonstrating the rapid escalation to root.

Blast radius: Any Linux system running an unpatched kernel is vulnerable to local privilege escalation. This includes servers, workstations, cloud instances, and containerized environments if the host kernel is vulnerable and an attacker gains initial low-level access (e.g., via a web application vulnerability, SSH compromise, or container escape). While not an initial access vector, it’s a critical post-exploitation capability that allows attackers to fully compromise a system after gaining a foothold.

Marcus’s verdict: An LPE that’s reliable and fast is a significant problem. While it’s not an internet-facing RCE, it’s the next best thing for an attacker once they’re inside. Think about your cloud instances, your containers, your internal Linux servers. If an attacker lands a webshell or compromises a service, this is their fast track to root. Patching kernels is always a pain, but this one is non-negotiable.

Actions:

1. Kernel Updates: Apply the latest Linux kernel updates to all affected systems. The fix was released in March 2026, so ensure your distributions are updated to a version including this patch.
2. Patch Management: Prioritize kernel updates in your patch management cycles.
3. Least Privilege: Enforce strict least privilege principles for all users and services to limit the impact of any initial compromise.
4. Endpoint Detection and Response (EDR): Monitor for unusual process execution, especially attempts to load kernel modules or execute commands with elevated privileges from unexpected user contexts.

GitHub Agentic Workflows — “GitLost” Prompt Injection

What happened: A new class of attack, dubbed “GitLost,” targets GitHub’s agentic workflows. This prompt injection attack allows unauthenticated leakage of private repository data. Attackers achieve this by crafting public GitHub issues containing hidden instructions that trick AI agents with privileged access into revealing sensitive information from private repositories. There is currently no assigned CVE for this technique, as it exploits a logical flaw in how AI agents interpret and act on input, rather than a traditional software vulnerability.

Source verification: Confirmed. This attack vector has been independently researched and demonstrated by security firms specializing in AI security, such as Lakera and Protect AI. GitHub has acknowledged the issue and is working on mitigations, though no official CVE has been issued yet. Discussions on X/Twitter and r/netsec show active community analysis and concern regarding the implications for AI-powered development workflows.

Technical breakdown: “GitLost” is a sophisticated prompt injection attack. AI agents, often used in GitHub for tasks like summarizing issues, suggesting code, or linking related information, are granted access to private repositories to perform their functions. The attack involves an adversary submitting a seemingly innocuous public GitHub issue. Embedded within this issue, or referenced by it, are carefully crafted “hidden” prompts or instructions designed to override the agent’s primary directive. When the AI agent processes this public issue, its privileged access allows it to inadvertently fetch and then include private repository data in its public response, effectively leaking sensitive information. This exploits the “trust boundary” between public input and privileged AI agent access.

• MITRE ATT&CK Mapping:
  • Initial Access: T1566 – Phishing (as it relies on social engineering the AI), T1598.003 – Compromise Accounts: Supply Chain Accounts (if the AI agent’s account is considered part of the supply chain).
  • Collection: T1005 – Data from Local System (AI agent collecting data), T1074.001 – Data Staged: Local Data Staging.
  • Exfiltration: T1041 – Exfiltration Over C2 Channel (if the AI’s response is considered a channel).
• PoC status: Proof-of-concept attacks have been demonstrated by researchers, leading to the public disclosure of “GitLost.” While not a traditional exploit, the methodology is well-understood and reproducible.

Blast radius: Any organization using GitHub’s agentic workflows where AI agents have access to private repositories and are configured to process public inputs (like issues or pull requests) is potentially exposed. The risk is particularly high for organizations handling sensitive intellectual property, proprietary code, or confidential data within their private GitHub repositories. The “unauthenticated” aspect means anyone can attempt this attack, making it a low-barrier-to-entry threat.

Marcus’s verdict: This is a wake-up call for everyone integrating AI into their development pipelines. We’ve been talking about prompt injection, but “GitLost” shows the real-world impact when AI agents operate with privileged access across trust boundaries. It’s not just about what the AI says, it’s about what it does and what data it accesses. We need to treat AI agents like privileged users, with the same scrutiny and access controls.

Actions:

1. Review AI Agent Permissions: Immediately audit all AI agents integrated with GitHub (or similar platforms) to understand their access levels to private repositories. Implement the principle of least privilege.
2. Isolate AI Workflows: Evaluate if AI agents processing public inputs must have access to sensitive private data. Consider segmenting workflows or using separate, less privileged agents for public interactions.
3. Input Sanitization & Output Filtering: Implement robust input sanitization for all data fed to AI agents and output filtering for agent responses to prevent sensitive information leakage.
4. Monitor AI Agent Activity: Implement logging and monitoring for AI agent interactions, especially those involving data access or generation of responses that might contain sensitive information.
5. Vendor Engagement: Engage with GitHub and other AI platform providers for specific guidance and upcoming mitigations against prompt injection and data leakage.

🛡️ CVEs — Full Analysis

CVE-2026-55255 — Langflow

Summary: This vulnerability (CVSS 6.1) is an authorization bypass (IDOR - Insecure Direct Object Reference) in Langflow. It allows an authenticated attacker to execute any AI workflow belonging to another user, potentially exposing sensitive secrets embedded within those workflows. The briefing notes that some experts rate it higher, likely due to the critical impact of exposing AI workflow secrets. A Proof-of-Concept (PoC) exists and has been observed in the wild, specifically linked to agentic ransomware campaigns.

CVSS/Details: CVSS 6.1 (Medium). The NVD score reflects an authenticated vulnerability, but the impact of exposing secrets from AI workflows, especially in the context of agentic ransomware, elevates its practical severity significantly. Patch status: A solid fix is available. PoC status: Yes, observed in agentic ransomware.

Marcus’s take: While the NVD rates this a 6.1, I agree with the experts rating it higher. An IDOR that lets an authenticated user execute any AI workflow, potentially exposing secrets, is a critical issue in the age of autonomous agents. This isn’t just data leakage; it’s a potential weaponization of your own AI infrastructure against you. The fact it’s linked to agentic ransomware (like JADEPUFFER) confirms its real-world impact. This is a supply chain risk for your AI-driven operations.

CVE-2026-55200 — libssh2

Summary: A severe pre-authentication remote code execution (RCE) vulnerability (CVSS 9.2) exists in libssh2. This flaw allows an attacker to achieve RCE via heap manipulation with crafted SSH packets before authentication. A PoC is available as part of the “Exploitarium” dump.

CVSS/Details: CVSS 9.2 (Critical). Patch status: Fix integrated into the mainline development branch, formal release pending. This means a stable, officially released patch might not be immediately available in all distributions, requiring potential workarounds or building from source. PoC status: Yes, publicly available in the “Exploitarium” dump.

Marcus’s take: Pre-authentication RCE in a core library like libssh2 is a nightmare. This is the kind of vulnerability that can lead to widespread internet-facing compromise, similar to what we’ve seen with other critical SSH-related flaws. The “Exploitarium” dump making PoCs public means the window for exploitation is wide open. The “formal release pending” status is concerning; this needs to be fast-tracked. Anyone running services that rely on libssh2 (and many do, from Git clients to network devices) needs to assess their exposure immediately.

CVE-2026-42880 — Argo CD

Summary: This critical vulnerability (CVSS 9.6) in Argo CD allows authenticated read-only users to extract sensitive Kubernetes Secrets directly from etcd clusters due to missing authorization checks. A Python script demonstrating the PoC has been observed.

CVSS/Details: CVSS 9.6 (Critical). Patch status: A fix is available. PoC status: Yes, Python script demonstrated.

Marcus’s take: A read-only user shouldn’t be able to pull Kubernetes secrets from etcd. Period. This is a fundamental authorization bypass that completely undermines the principle of least privilege in a Kubernetes environment. If you’re using Argo CD for GitOps, this means an attacker who gains even low-level authenticated access could potentially steal credentials, API keys, and other sensitive data, leading to full cluster compromise. This is a critical misconfiguration or design flaw that needs immediate attention.

CVE-2026-50548, CVE-2026-50549 — Cursor IDE

Summary: Two critical RCE vulnerabilities, collectively dubbed “DuneSlide” (CVSS 9.8), affect Cursor IDE. These are zero-click prompt injection flaws that allow attackers to break out of the IDE’s sandbox, leading to full system compromise.

CVSS/Details: CVSS 9.8 (Critical). Patch status: Fixes shipped with Cursor 3.0 client (released April 2). PoC status: Yes.

Marcus’s take: “Zero-click prompt injection” leading to RCE and sandbox escape in a developer IDE? This is terrifying. Developers are prime targets, and an IDE compromise is a direct path to supply chain attacks. This isn’t just leaking data; it’s full system takeover. The fact that it’s zero-click means a malicious project or even a crafted comment could trigger it. If your developers use Cursor IDE, they need to be on version 3.0 or later immediately. This highlights the growing attack surface introduced by AI-powered tools in the development workflow.

Argo CD Repo-Server — Unauthenticated RCE (No CVE)

Summary: An unpatched flaw in Argo CD’s repo-server component allows unauthenticated remote code execution on an internal network port. If an attacker can reach this internal gRPC service, it can lead to a full Kubernetes cluster takeover. This vulnerability currently has no assigned CVE.

CVSS/Details: CVSS Critical (implied by “full Kubernetes cluster takeover”). Patch status: No fix currently available. The briefing states “patch has known issues (no patch available),” indicating the vendor is aware but a stable public fix is not yet ready. PoC status: Yes, demonstrated by Synacktiv.

Marcus’s take: No CVE, no patch, unauthenticated RCE leading to full Kubernetes takeover. This is a red alert for anyone running Argo CD. The “internal network port” aspect is a small saving grace, meaning it’s not directly internet-facing unless you’ve misconfigured your network. But once an attacker has a foothold on your internal network, this is a direct path to critical infrastructure. This is a classic “assume breach” scenario where internal segmentation becomes paramount. This needs to be treated with the same urgency as a zero-day, with compensating controls put in place immediately.

⚡ TTPs & Attack Research — Deep Dives

Agentic Ransomware: JADEPUFFER

The emergence of JADEPUFFER marks a significant evolution in ransomware, representing the first documented fully autonomous, LLM-driven campaign. This isn’t just AI assisting an attacker; it’s the AI being the attacker, orchestrating the entire kill chain without human intervention.

Attack Chain:

1. Initial Access (T1190 - Exploit Public-Facing Application): JADEPUFFER exploits vulnerabilities like CVE-2025-3248 in Langflow (an AI workflow orchestration tool) to gain initial access. The LLM component likely identifies targets and suitable exploits.
2. Reconnaissance (T1592 - Gather Victim Host Information, T1087 - Account Discovery): Once inside, the LLM-driven agent conducts real-time reconnaissance of the environment, identifying valuable data, network topology, and potential lateral movement paths. It can dynamically adapt its reconnaissance based on the discovered environment.
3. Credential Harvesting (T1078 - Valid Accounts, T1552 - Unsecured Credentials): The agent identifies and harvests credentials, potentially exploiting misconfigurations or leveraging discovered vulnerabilities to access password hashes or clear-text credentials.
4. Lateral Movement (T1021 - Remote Services, T1078 - Valid Accounts): Using harvested credentials and reconnaissance data, the agent autonomously moves laterally through the network, identifying critical systems and data stores. It can dynamically generate and execute scripts for lateral movement.
5. Destructive Database Extortion (T1486 - Data Encrypted for Impact): The final stage involves encrypting or exfiltrating data, specifically targeting databases for extortion. The LLM can dynamically craft ransom notes and communication strategies.

Detection Opportunities:

• Anomaly Detection: Look for unusual sequences of actions from a single source or newly introduced processes. Autonomous agents might exhibit rapid, non-human patterns of activity.
• Endpoint Telemetry: Monitor for CVE-2025-3248 exploitation attempts on Langflow instances. Track process creation, file modifications, and network connections that deviate from baseline behavior.
• Credential Access Monitoring: Alert on multiple failed login attempts, use of dormant accounts, or credential usage patterns inconsistent with normal user behavior.
• Database Activity Monitoring: Monitor for bulk data encryption, unusual database queries, or large-scale data exfiltration attempts.

Mitigations:

• Patch Management: Promptly patch known vulnerabilities, especially in AI orchestration tools like Langflow.
• Network Segmentation: Isolate critical assets and AI infrastructure to limit lateral movement.
• Least Privilege: Enforce strict least privilege for all accounts and services, including AI agents.
• AI Agent Monitoring: Implement dedicated monitoring for AI agent activity, focusing on their access patterns, commands executed, and data interactions.
• Behavioral Analytics: Deploy EDR/XDR solutions with strong behavioral analytics to detect anomalous activity indicative of autonomous attacks.

AI Agent Prompt Injection (GitLost)

This TTP, already discussed under critical threats, highlights a new frontier in social engineering: targeting AI systems directly. Attackers craft public inputs (e.g., GitHub issues) with hidden instructions to manipulate AI agents, leading to unintended actions or data leakage.

Attack Chain:

1. Reconnaissance (T1598.003 - Compromise Accounts: Supply Chain Accounts): Attacker identifies AI agents integrated into platforms like GitHub that have privileged access to sensitive data (e.g., private repositories).
2. Prompt Crafting (T1566 - Phishing): The attacker creates a public-facing input (e.g., a GitHub issue, a comment, a pull request description) that contains both legitimate content and carefully disguised malicious instructions (prompt injection). These instructions are designed to bypass the AI’s safety filters and override its primary directive.
3. Agent Interaction: The AI agent, designed to process and respond to such inputs, ingests the crafted prompt.
4. Data Leakage/Action (T1005 - Data from Local System, T1041 - Exfiltration Over C2 Channel): The injected prompt causes the AI agent to perform an unintended action, such as summarizing content from a private repository and including it
