CVE-2026-89182

MEDIUM 5.4 PoC AVAILABLE

Published 2026-10-06 · Last modified 2026-10-07

With `[repository] FORCE_PRIVATE = true`, Gitea creates new repositories as private, but the post-receive hook still applied the `repo.private=false` push option to an empty repository created by push. Any user who can create repositories could make their new repository public in violation of the instance policy. The default configuration is not affected.

EXPLOIT AVAILABLE

Public exploit or PoC code exists. Modeled probability is still low, but the barrier to attack is reduced — watch closely.
