Google Analyticator < 6.5.6 is vulnerable to Admin+ PHP Object Injection vulnerability

The Google Analyticator plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 6.5.5 via deserialization of untrusted input. This allows administrator-level attackers to inject a PHP Object. The additional presence of a POP chain in the vulnerable plugin may allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
