The walk checked that each candidate repository existed, but never that the caller could read it.\n\nA request for a path inside a private repository, such as `GET /secret/anything?go-get=1`, therefore returned `200` naming `secret` and its clone URL, even though `GET /secret?go-get=1` correctly returned `404`. The same `?go-get=1` exception in the HTTP access middleware also let requests reach the LFS and dumb-HTTP routes with the repository existence check skipped, where two LFS handlers dereferenced the missing repository and panicked.\n\nThe same disclosure appears without `?go-get=1`. The Git and LFS routes answered a repository the caller could not read differently depending on whether it existed: an anonymous clone of a private repository got `401` while a missing one got `404`, and a signed-in user without access got the reverse pattern. Either way, one request confirms whether a guessed name is a private repository. This was found while fixing the go-get issue and is included here","public_affected_ranges":[">= 0.5.0, < 0.12.3"]}],"null_published_at":"2026-10-31T22:13:31.276Z","source_updated_at":"2026-10-30T14:42:37.000Z","source_disclosed_at":"2026-10-30T14:42:35.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:55:49.621Z"}],"next_cursor":null,"snapshot_revision":"42594"}
