Affected Installs
All 1.5.x installs prior to and including 1.5.14 are affected.

Solution
Turn on Apache mod_rewrite and configure your .htaccess file to filter out XML files. In the htaccess.txt file shipped with version 1.5.15, lines 35-39 contain example code that will deny access to XML files. You can incorporate this code (or similar code) into your .htaccess file. Be sure to test that it does not cause problems on your site.
