How the CVE Works:
The vulnerability in `reviewdog/action-setup@v1` arises from a malicious commit (f0d342d) that was introduced into the codebase. This commit injects malicious code designed to extract and expose sensitive secrets from GitHub Actions workflow logs. The compromised code was active between March 11, 2025, 18:42 UTC and 20:31 UTC. Any GitHub Actions workflow using `reviewdog/action-setup@v1` or dependent actions (e.g., action-shellcheck, action-staticcheck) would inadvertently execute this malicious code, regardless of version pinning or usage method. The malicious code logs sensitive data, such as API keys, tokens, and other secrets, into the workflow logs, making them accessible to attackers.
DailyCVE Form:
Platform: GitHub Actions
Version: reviewdog/action-setup@v1
Vulnerability: Secret Exposure
Severity: Critical
Date: March 11, 2025
What Undercode Say:
Exploitation:
- Malicious Code Execution: Attackers injected code into `reviewdog/action-setup@v1` to dump secrets into logs.
- Workflow Logs: Sensitive data is exposed in GitHub Actions workflow logs, accessible to anyone with log access.
- Dependent Actions: All actions relying on `reviewdog/action-setup@v1` are compromised, regardless of version pinning.
Protection:
- Immediate Action: Upgrade to `reviewdog/action-setup@3f401fe` or later to mitigate the vulnerability.
- Audit Workflows: Review all GitHub Actions workflows for usage of `reviewdog/action-setup@v1` or dependent actions.
- Secrets Management: Use GitHub’s built-in secrets management to avoid hardcoding sensitive data in workflows.
- Log Monitoring: Regularly monitor workflow logs for unexpected data exposure.
Commands:
1. Upgrade Action:
- uses: reviewdog/action-setup@v2
2. Audit Workflows:
grep -r "reviewdog/action-setup@v1" .github/workflows/
3. Rotate Secrets:
gh secret set --env ENV_NAME --body "new_secret_value"
Code Snippets:
1. Secure Workflow Example:
jobs: secure-job: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - uses: reviewdog/action-setup@v2 - run: echo "Safe workflow"
2. Log Filtering:
- name: Filter sensitive logs
run: |
echo "::add-mask::${{ secrets.API_KEY }}"
Analytics:
- Impact: High, as secrets exposure can lead to unauthorized access and data breaches.
- Affected Users: All GitHub Actions users relying on `reviewdog/action-setup@v1` or dependent actions.
- Mitigation Rate: Rapid, due to quick patching by maintainers and community awareness.
By following these steps, users can protect their workflows from this critical vulnerability and prevent further exploitation.
