W3 Total Cache Fixes Security Hole

Recently announced by Sucuri Security, WordPress caching plugin W3 Total Cache had a security hole.

The issue is connected to the way W3TC stores the database cache (in a public accessible directory). It can be used to retrieve password hashes and other database information.

Sucuri outlined a fix for the issue as an interim solution:

It seems the easiest way to protect your sites is by disabling database cache or creating an .htaccess file inside the wp-content/w3tc directory denying direct access there:

deny from all

WP Force was a victim of this security hole, but measures were taken to secure all data on the site and its users of the site. The fix worked and the site was never compromised after an investigation.

Four days after the announcement of the security hole, W3 Total Cache owner Frederick Townes, released an update.
