Gogs is an open source self-hosted Git service. Versions 0.13.4 and below have a broken access control vulnerability which allows authenticated users with write access to any repository to modify labels belonging to other repositories. The UpdateLabel function in the Web UI (internal/route/repo/issue.go) fails to verify that the label being modified belongs to the repository specified in the URL path, enabling cross-repository label tampering attacks. The vulnerability exists in the Web UI's label update endpoint POST /:username/:reponame/labels/edit. The handler function UpdateLabel uses an incorrect database query function that bypasses repository ownership validation. This issue has been fixed in version 0.14.1.
AnalysisAI
Gogs versions 0.13.4 and earlier contain an access control bypass in the label management function that allows authenticated users to modify labels across repositories they don't own. The vulnerability stems from insufficient validation in the label update endpoint, enabling cross-repository label tampering attacks. Public exploit code exists for this issue, though a patch is available in version 0.14.1.
