CVE-2026-1322Public exploitNetwork attack vector

Authenticated private-project writes via read-only OAuth scope

Published May 14, 2026 · Updated May 14, 2026

Improper authorization in GitLab CE/EE allows remote authenticated users to create issues and comments in private projects. Issue and comment creation endpoints accept state-changing API requests made with OAuth tokens limited to the read_api scope. A valid user context and a read_api-scoped OAuth application are required; successful requests alter private-project issue content without interrupting service.
