CVSS 4.3 (Medium)
Publicly Published October 30, 2022

Researcher István Márton - Wordfence


The Appointment Booking Calendar plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the cpabcal_feedback() function in versions up to, and including, 1.3.69. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to submit plugin feedback. This can also be exploited via CSRF due to missing nonce validation.
