CVE-2026-52810: Gogs allows users to write to readonly repositories using receive-pack + service=git-upload-pack confusion

June 23, 2026

Git smart HTTP authorizes POST …/git-receive-pack using the client-supplied service query string (so ?service=git-upload-pack is evaluated as read access) while routing still runs git receive-pack, allowing push where only read should be allowed.
