| CVE-2026-1932 | Med | 0.34 | 5.3 | 0.00 | Feb 14, 2026 | The Appointment Booking Calendar Plugin – Bookr plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the update-appointment REST API endpoint in all versions up to, and including, 1.0.2.

| CVE-2025-13317 | Med | 0.34 | 5.3 | 0.00 | Nov 22, 2025 | The Appointment Booking Calendar plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.3.96. This is due to the plugin exposing an unauthenticated booking processing endpoint (cpabc_appointments_check_IPN_verification) that trusts attacker-supplied payment notifications without verifying their origin, authenticity, or requiring proper authorization checks. This makes it possible for unauthenticated attackers to arbitrarily confirm bookings and insert them into the live calendar via the 'cpabc_ipncheck' parameter, triggering administrative and customer notification emails and disrupting operations. | |
| CVE-2026-1083 | Med | 0.29 | 4.4 | 0.00 | Jan 28, 2026 | The Appointment Hour Booking – Booking Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via form field configuration parameters in all versions up to, and including, 1.5.60 due to insufficient input sanitization and output escaping on the 'Min length/characters' and 'Max length/characters' field configuration values. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the form builder interface. This only affects multi-site installations and installations where unfiltered_html has been disabled. |
