Gogs is an open source self-hosted Git service.
CVSS 9.3 Critical EPSS 1.4% · p72
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 1.4%, percentile 72: FIRST’s model estimates a 1.4% chance of exploitation activity in the next 30 days, higher than 72% of all scored CVEs (moderate). 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.
- Only applies if your dependency tree includes
gogs.io/gogs(Go) <= 0.13.3, fixed in 0.13.4. Check your lockfile, including transitive dependencies.
What it is
Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, due to the insufficient patch for CVE-2024-56731, it's still possible to update files in the .git directory and achieve remote command execution. This issue has been patched in versions 0.13.4 and 0.14.0+dev.
From the GitHub advisory
Summary Due to the insufficient patch for the https://github.com/gogs/gogs/security/advisories/GHSA-wj44-9vcg-wjq7, it's still possible to update files in the .git directory and achieve remote command execution.
