CVE-2026-123012
CVE-2026-123012 updated by NVD
Summary
In Gogs 0.14.3, the Git Smart HTTP authorization layer in internal/route/repo/http.go allows a push when only read access was intended, a different vulnerability than CVE-2026-52810. This occurs because of a case-sensitivity desync between the authorization classifier and the request dispatcher: the gitHTTPIsPull function compares the Git action verb case-sensitively and defaults to pull (read access) for any unrecognized string, whereas the request dispatcher lowercases the same verb before routing it to the receive-pack handler. Capitalizing a single letter in the URL (e.g. info/Refs instead of info/refs, or git-receive-Pack instead of git-receive-pack) causes the classifier to misidentify a push as a pull, granting only read-level authorization, whereas the dispatcher routes it to the write handler. An authenticated read-only collaborator can exploit this to push to a private repository, creating, updating, or deleting refs.
