Description

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.

Affected products

Gitea Open Source Git Server: through 1.27.2
