New Wordpress vulnerability - Protect your website

Thursday, April 25, 2013

There is a new serious WordPress vulnerability in certain versions of two popular WordPress caching plugins, W3TC and WP Super Cache. The vulnerability allows remote PHP code to be executed locally on a server for anyone running either of the plugins. An attacker could then execute code on the infected server.
