Description
The Smart Appointment & Booking plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and a nonce validation logic flaw in the saab_cancel_booking() function in all versions up to, and including, 1.0.8. The nonce check uses && (AND) instead of || (OR), which means providing any value for the security parameter causes the entire check to be skipped. This makes it possible for unauthenticated attackers to cancel arbitrary bookings by supplying a predictable booking ID.
