Summary

Gitea through 1.27.2 has improper access control (CWE-284) in its package registry. Its read access check for packages owned by Limited-visibility users does not exclude restricted accounts, so an authenticated restricted user can enumerate and download those packages despite the visibility policy. The issue exposes package contents across the intended authorization boundary for user-owned package registries.

Description from the CNA

Gitea's package registry grants authenticated users read access to packages owned by Limited-visibility users without excluding restricted accounts. A restricted user can enumerate and download those packages despite the visibility policy that should prevent this access. The issue affects user-owned package registries and exposes package contents across the intended authorization boundary.
