Description
The Filter Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.4. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the title and content of arbitrary WordPress posts, write the _wp_attachment_image_alt meta key on arbitrary posts, and create or overwrite arbitrary ufg_gallery_* options.
