CVE-2026-5693
Medium · 5.3
CWE-862 May 12, 2026
Smart Appointment & Booking <= 1.0.8 - Missing Authorization to Unauthenticated Arbitrary Booking Cancellation
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.

CWE-79 Feb 4, 2026
Smart Appointment & Booking <= 1.0.7 - Authenticated (Subscriber+) Stored Cross-Site Scripting via saab_save_form_data AJAX Action
The Smart Appointment & Booking plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the saab_save_form_data AJAX action in all versions up to, and including, 1.0.7 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
