PropertyHive < 2.0.6 - Unauthenticated PHP Object Injection via propertyhive_currency

Description

The PropertyHive plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.0.5 via deserialization of untrusted input from the 'propertyhive_currency' cookie value. This makes it possible for unauthenticated attackers to inject a PHP Object. No POP chain is present in the vulnerable plugin. 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.
