An attacker can manually modify the request payload and assign themselves elevated privileges. Because the backend does not enforce role assignment restrictions or ignore client-supplied role parameters, the server accepts the manipulated value and creates the account with SUPER_ADMIN privileges. This allows any unauthenticated attacker to register a fully privileged administrative account."}], "lastModified": "2026-03-12T21:08:22.643", "sourceIdentifier": "security-advisories@github.com"}
