EUVD-2025-27053

Comprehensive Technical Analysis of EUVD-2025-27053

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-27053 pertains to Roo Code, an AI-powered autonomous coding agent. Specifically, versions 3.26.6 and below are affected by a critical flaw in a GitHub workflow that processes unsanitized pull request metadata in a privileged context. This vulnerability allows for Remote Code Execution (RCE) on the Actions runner, which has broad permissions and access to repository secrets.

Severity Evaluation:

• Base Score: 9.9 (Critical)
• Base Score Version: 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:N

The high base score indicates a severe vulnerability due to the following factors:

• Attack Vector (AV:N): Network-based attack, meaning it can be exploited remotely.
• Attack Complexity (AC:L): Low complexity, indicating that the attack does not require specialized conditions.
• Privileges Required (PR:N): No privileges are required to exploit the vulnerability.
• User Interaction (UI:N): No user interaction is required.
• Confidentiality (VC:H), Integrity (VI:H), and Availability (VA:H): High impact on all three aspects.
• Scope Change (SC:H): The vulnerability affects components beyond its security scope.
• Impact on Integrity (SI:H): High impact on the integrity of the system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Malicious Pull Requests: An attacker can craft a pull request with malicious metadata.
• Unsanitized Input: The GitHub workflow processes this metadata without proper sanitization, leading to RCE.

Exploitation Methods:

• Arbitrary Command Execution: The attacker can execute arbitrary commands on the Actions runner.
• Repository Manipulation: The attacker can push or modify code in the repository.
• Secrets Access: The attacker can access repository secrets.
• Malicious Releases: The attacker can create malicious releases or packages, compromising the repository and associated services.

3. Affected Systems and Software Versions

Affected Systems:

• Roo Code: Versions 3.26.6 and below.

Software Versions:

• Roo Code < 3.26.7: All versions prior to 3.26.7 are vulnerable.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade to Version 3.26.7: Users should immediately upgrade to Roo Code version 3.26.7 or later.
• Review and Sanitize Inputs: Ensure that all inputs, especially metadata from pull requests, are properly sanitized.
• Limit Permissions: Reduce the permissions of the Actions runner to the minimum necessary.
• Monitor for Suspicious Activity: Implement monitoring to detect and respond to any suspicious activities in the repository.

Long-Term Strategies:

• Regular Security Audits: Conduct regular security audits of GitHub workflows and other automated processes.
• Implement Security Best Practices: Follow best practices for securing CI/CD pipelines and automated workflows.
• Educate Developers: Train developers on secure coding practices and the importance of input validation.

5. Impact on European Cybersecurity Landscape

The vulnerability in Roo Code poses a significant risk to the European cybersecurity landscape, particularly for organizations that rely on automated coding agents and CI/CD pipelines. The potential for complete repository compromise and the ability to access sensitive secrets can lead to data breaches, unauthorized code modifications, and the distribution of malicious software. This underscores the need for robust security measures in automated development tools and the importance of timely patching and updates.

6. Technical Details for Security Professionals

Vulnerability Details:

• CVE ID: CVE-2025-58371
• Assigner: GitHub_M
• References:
  • GitHub Security Advisory
  • Fix Commit

ENISA IDs:

• Product: Roo-Code (ID: 992a09c8-66ac-35f6-8d7e-83980520a11d)
• Vendor: RooCodeInc (ID: 970ff061-f868-33e4-8ca3-94f6581c2a7d)

Technical Recommendations:

• Input Validation: Implement robust input validation mechanisms to sanitize all metadata and inputs.
• Least Privilege Principle: Apply the principle of least privilege to all automated workflows and runners.
• Regular Updates: Ensure that all development tools and dependencies are regularly updated to the latest secure versions.
• Incident Response Plan: Develop and maintain an incident response plan to quickly address and mitigate any security breaches.

By addressing this vulnerability promptly and implementing the recommended mitigation strategies, organizations can significantly reduce the risk of exploitation and protect their development environments from potential attacks.
