CVE-2026-87965: Unknown Easy Appointments

Medium severity, CVSS 4.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Unknown Easy Appointments: before 4.0.2.2 (fixed in 4.0.2.2)
