CVE-2017-20206 Critical · 9.8 CWE-502 Oct 18, 2025
Appointments <= 2.2.1 - Unauthenticated PHP Object Injection
The Appointments plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.2.1 via deserialization of untrusted input from the `wpmudev_appointments` cookie. This allows unauthenticated attackers to inject a PHP Object. Attackers were actively exploiting this vulnerability with the WP_Theme() class to create backdoors.
