CVE-2026-116296: Gitea API mutation enforcement bypass on archived repositories

CVE-2026-116296 · Severity: info · Published 2026-11-01

Gitea is a self-hosted Git platform that allows organizations to manage repositories and their metadata. Users with write access to archived repositories—which should be read-only—could modify release assets, delete releases, and edit milestones and labels through the API despite the web interface blocking such changes. This allowed attackers to corrupt repository records and release data on repositories intended to be immutable.

Technologies: Gitea. Vendors: Gitea.

Technical details

The vulnerability exists in Gitea's API routes for releases, release assets, milestones, and repository labels, which did not validate whether a repository was archived before allowing mutation operations. An authenticated user with write access to an archived repository, or a holder of such a user's write-scoped token, could bypass read-only enforcement to modify or delete release assets while preserving download URLs, delete releases and tags, and create/edit/delete milestones and labels. The fix adds validation to reject these operations with HTTP 423 Locked responses on archived repositories.
