Asgaros Forum < 2.8.0 - Unauthenticated PHP Object Injection in prepare_unread_status

Description

The Asgaros Forum plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.7.2 via deserialization of untrusted input in the prepare_unread_status function. This makes it possible for unauthenticated attackers to inject a PHP Object. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
