Alert meAnalysisAIv1 – Mar 12, 2026
Gogs versions 0.13.3 and earlier fail to enforce write permissions on the repository contents endpoint, allowing attackers with read-only access to modify files, create commits, and execute git push operations. An authenticated user possessing only read permissions can bypass authorization checks and gain unauthorized write access to repository contents. This affects self-hosted Gogs instances and has no patch currently available for affected versions.
Earlier versions of this analysis (1)
Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, the endpoint "PUT /repos/:owner/:repo/contents/*" does not require write permissions and allows access with read permission only via repoAssignment(). [CVSS 6.5 MEDIUM]
RemediationAI
Monitor vendor advisories for a patch. Restrict network access to the affected service where possible.

Classified as CWE-862 (Missing Authorization). Affects Gogs. Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, the endpoint "PUT /repos/:owner/:repo/contents/*" does not require write permissions and allows access with read permission only via repoAssignment(). After passing the permission check, PutContents() invokes UpdateRepoFile(), which results in commit creation and the execution of git push. As a result, a token with read-only permission can be used to modify repository contents. This issue has been patched in versions 0.
