CVE-2025-30154
Remediation/Mitigation Strategy for CVE-2025-30154
This document outlines the remediation and mitigation strategy for CVE-2025-30154, affecting the reviewdog/action-setup@v1 GitHub Action.
1. Vulnerability Description:
- Vulnerability: Compromised GitHub Action
- Affected Component:
reviewdog/action-setup@v1and other reviewdog actions that use it:reviewdog/action-shellcheck,reviewdog/action-composite-template,reviewdog/action-staticcheck,reviewdog/action-ast-grep, andreviewdog/action-typos. - Description: The
reviewdog/action-setup@v1GitHub Action was compromised between 18:42 and 20:31 UTC on March 11, 2025. Malicious code was injected to dump exposed secrets to GitHub Actions Workflow Logs. This means that any workflow using the compromised version or any of the affected reviewdog actions (regardless of the version specified) could potentially leak sensitive information. - Data Leaked: Exposed secrets including, but not limited to, API keys, passwords, tokens, and other sensitive credentials stored within GitHub Actions environments.
2. Severity:
- CVSS Score: 8.6 (High)
- Severity Level: High
- Impact: High Confidentiality Impact (potential for significant data breach)
3. Known Exploit:
- Exploit Details: The injected malicious code within
reviewdog/action-setup@v1actively dumps sensitive information from the GitHub Actions environment variables into the workflow logs. These logs are potentially accessible to users with the necessary permissions within the GitHub repository (e.g., administrators, collaborators).
4. Remediation/Mitigation Strategy:
The following steps should be taken immediately to mitigate the impact of this vulnerability:
Immediate Action: Audit GitHub Actions Workflow Logs:
- Thoroughly review all GitHub Actions workflow logs generated between March 11, 2025, 18:42 UTC and March 19, 2025, 16:15:34 UTC. This is the period where the compromised action could have been actively leaking secrets.
- Search for any evidence of sensitive data being logged, such as API keys, passwords, tokens, or environment variables containing confidential information. Look for unusual patterns, base64 encoded strings, or anything resembling secret key formats.
Revoke Compromised Credentials:
- Critical Step: Assume all secrets potentially exposed in the affected workflow logs have been compromised.
- Immediately revoke and rotate all potentially leaked credentials. This includes:
- API keys
- Passwords
- Tokens (OAuth, Personal Access Tokens, etc.)
- SSH keys
- Any other sensitive credentials stored as secrets or environment variables used in the affected workflows.
- Notify the service providers associated with the revoked credentials about the potential breach to prevent further misuse.
Update Workflows (Remove Vulnerable Actions):
- Remove all instances of
reviewdog/action-setup@v1from your workflows. - Remove any usage of
reviewdog/action-shellcheck,reviewdog/action-composite-template,reviewdog/action-staticcheck,reviewdog/action-ast-grep, andreviewdog/action-typosduring the affected period. Even if you specify a different version or pin to a specific commit, the underlying issue stems from the dependency on the compromisedreviewdog/action-setup@v1within these actions. - Alternatives: Consider alternative solutions for the functionality provided by these actions or explore updated versions (if available) released by the maintainers after confirmation of a clean build. Thoroughly vet any replacement actions before implementation.
- Remove all instances of
Monitor for Suspicious Activity:
- Actively monitor your infrastructure, systems, and accounts for any unusual activity that might indicate the use of compromised credentials. This includes:
- Unauthorized access attempts
- Unexpected API calls
- Changes to configurations
- Unusual resource consumption
- Implement or enhance intrusion detection and prevention systems (IDS/IPS) to identify and block malicious activities.
- Actively monitor your infrastructure, systems, and accounts for any unusual activity that might indicate the use of compromised credentials. This includes:
Incident Response and Forensics:
- Initiate your incident response plan to thoroughly investigate the incident.
- Collect and preserve all relevant evidence, including workflow logs, system logs, and network traffic.
- Consider engaging a security forensics expert to assist with the investigation and determine the full extent of the compromise.
Post-Incident Review and Security Hardening:
- Conduct a post-incident review to identify the root cause of the vulnerability and any weaknesses in your security posture.
- Implement additional security measures to prevent similar incidents in the future, such as:
- Dependency Scanning: Implement automated dependency scanning tools to detect and alert on vulnerabilities in your project dependencies, including GitHub Actions.
- Supply Chain Security: Strengthen your supply chain security practices to ensure the integrity and trustworthiness of third-party components. Consider using tools that verify the provenance of actions and dependencies.
- Least Privilege Principle: Apply the principle of least privilege to limit the access rights of service accounts and users.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities proactively.
- Secrets Management: Implement a robust secrets management solution to securely store and manage sensitive credentials. Avoid storing secrets directly in environment variables or configuration files.
- Regular Rotation of Secrets: Enforce regular rotation of secrets to minimize the impact of potential compromises.
- Workflow Log Sanitization: Explore options to sanitize workflow logs and redact sensitive information before they are stored.
Communicate: Inform relevant stakeholders (e.g., developers, security team, management) about the incident and the remediation efforts.
Important Considerations:
- Trust No One: Assume that all secrets potentially exposed during the affected period are compromised.
- Time is of the Essence: Act quickly to revoke and rotate compromised credentials to minimize the potential damage.
- Comprehensive Review: Thoroughly review all workflow logs and systems for any evidence of unauthorized access or activity.
- Long-Term Security: Implement long-term security measures to prevent similar incidents in the future.
This strategy provides a comprehensive approach to remediating and mitigating the impact of CVE-2025-30154. Remember to adapt these steps to your specific environment and requirements.
