Security Issue : timthumb.php

Suffusion doesn’t have TimThumb. You can verify the source code from the official WP repository: http://themes.svn.ww.wp.xz.cn/suffusion/4.4.4/. The last version of Suffusion to have TimThumb was 3.7.1, which was almost 2 years back. In fact I took TimThumb out of Suffusion 6 months before the TimThumb vulnerability was discovered.

Attackers try thousands of random strings in the hopes of injecting malicious code, but rest assured that TimThumb is not a part of the Suffusion code. Moreover, every theme distributed through http://ww.wp.xz.cn/extend/themes/ goes through a review, and TimThumb is not allowed in your code. So there is no theme on this site that has TimThumb in it.
