CVE-2026-28740Network attack vector

Private LFS disclosure via broad repository access

Published Jul 3, 2026 · Updated Jul 3, 2026

Incorrect authorization in Gitea 1.26.2 and earlier allows remote authenticated users to disclose private Git LFS objects through object reuse. The LFSObjectAccessible helper passes unit.TypeInvalid to AccessibleRepositoryCondition, treating broad repository access as authorization for a source object instead of requiring Code-unit access. Exploitation requires Code write access to a target repository, non-Code access to a private source repository, and knowledge of an object OID and size; successful reuse exposes that object through the target repository.
