# CVE-2025-30154: reviewdog/action-setup GitHub Action Embedded Malicious Code Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run reviewdog action-setup GitHub Action. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-03-24, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-04-14 ; treat that as the outer limit, not the target.
- EPSS 2.5% , percentile 84: FIRST’s model estimates a 2.5% chance of exploitation activity in the next 30 days, higher than 84% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Editorial verdict: Check exposure. tj-actions/changed-files: GitHub Action Leaked CI Secrets — The malicious tags were cleaned up within about a day in March 2025; today the job is confirming you rotated any secret that a March 14-15, 2025 workflow run could have printed, and that you pin Actions by SHA.
