The Image Optimizer by 10web plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 1.0.26 via the dir parameter in the get_subdirs AJAX function. This allows authenticated attackers with administrator-level permissions or above to view the directory structure of arbitrary folders on the server, though it does not reveal or provide access to any files.
