Description
Zipline through 4.4.0 contains an authentication bypass vulnerability in the WebAuthn login endpoint that creates sessions for a supplied registered credential ID without verifying the assertion. Attackers who obtain a target's passkey credential ID can impersonate that account without its authenticator, potentially gaining administrative control over SUPERADMIN accounts.
