For the people not yet on the latest WooFramework version: You can download the latest version of WooFramework here: http://cl.ly/2a3j1m351C3u2i0t122j (it is 5.3.10)
Do you know how to manually update the framework? This zip file unzips to a "framework" folder, you need to replace to contents of the "functions" folder of your theme. Obviously make a backup of everything before you start.
This exploit is fixed in the latest two stable builds and should have been reported to us (WooThemes team) in the first place. Wonder if this guy has ever heard of the concept of responsible disclosure...
