Advisory
Source description from Wordfence Intelligence, credited to WPScanTeam.
The WooLentor plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.5.3 via deserialization of untrusted input in the function woolentor_set_views_count, which unserializes a user-provided cookie. This allows 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.
