Technical description
The Popover Windows plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on multiple ajax actions (e.g., pop_submit, poptheme_submit) in all versions up to, and including, 1.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify the plugin's settings and content.
