The Yet Another Stars Rating plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.8.6 via deserialization of untrusted input from the unserialize() function found in the yasr-shortcode-functions.php file. This allows unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to remotely execute arbitrary code.
