CVE-2026-52813: Gogs has Path Traversal in organization name that results in RCE through Git hooks
Gogs is an open source self-hosted Git service.
CVSS 10.0 Critical EPSS 1.1% · p66
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 1.1%, percentile 66: FIRST’s model estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 66% 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) < 0.14.3, fixed in 0.14.3. Check your lockfile, including transitive dependencies.
What it is
Gogs is an open source self-hosted Git service. Prior to 0.14.3, organization names containing path traversal sequences (../) are accepted by Gogs, and repositories under them are written to paths following these path traversals. This allows storing/retrieving data for repositories at arbitrary locations on the filesystem. By creating nested structure of Git repositories, one can overwrite the other's hooks configuration to result in Remote Code Execution (RCE). This vulnerability is fixed in 0.14.3.
From the GitHub advisory
Summary
Organization names containing path traversal sequences (../) are accepted by Gogs, and repositories under them are written to paths following these path traversals. This allows storing/retrieving data for repositories at arbitrary locations on the filesystem. By creating nested structure of Git repositories, one can overwrite the other's hooks configuration to result in Remote Code Execution (RCE).
Details
During organization creation, internal/database/org.go calls os.MkdirAll(repox.UserPath(org.Name)) without sanitizing org.Name.
