Title
Easy Appointments < 4.0.2.2 - Unauthenticated Appointment Cancellation/Confirmation via Forgeable Email-Link Token
Summary
The Easy Appointments WordPress plugin before 4.0.2.2 does not use an unguessable token to authorize its mail-link appointment cancellation and confirmation action, deriving the token from a hardcoded source-embedded salt and the appointment's creation timestamp, so unauthenticated attackers who know or guess that timestamp can cancel or confirm arbitrary appointments.
Severity
No CVSS data available.
