Description
The W3 Total Cache plugin for WordPress is vulnerable to authorization bypass due to the use of loose comparison on the nonce value in the /pub/apc.php file. This affects versions up to, and including, 0.9.4.1. This makes it possible for attackers to bypass nonce protections if a valid nonce starts with 0e. In the right situation this bypass can be used to empty the OPCache.
