Technical details
The vulnerability is a broken access control issue (CWE-284) in the appointment confirmation/cancellation email link handler. The plugin derives authorization tokens from a hardcoded salt and the appointment's creation timestamp, rather than using cryptographically random, unguessable tokens. An unauthenticated attacker with knowledge of or ability to guess an appointment's creation timestamp can forge a valid token and modify any appointment's status via network requests to the email-link handler. No authentication or user interaction is required. The vulnerability is fixed in version 4.0.2.2.
