CVE-2026-66849

Gitea restricted-user package visibility bypass

4.3 Medium

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.
