CVE-2026-66849Network attack vectorHinoki check available

Package disclosure via missing restricted-account authorization

Published Oct 14, 2026 · Updated Oct 14, 2026

Authorization bypass in Gitea 1.27.2 and earlier allows remote authenticated users to read other users' packages via registry requests. The user-owner branch of determineAccessMode grants read access for Limited-visibility owners without checking whether the requesting account is restricted. An authenticated restricted account can enumerate and download those owners' package contents; the documented impact is disclosure, not package modification.
