Image Photo Gallery Final Tiles Grid < 3.6.10 - Missing Authorization to Authenticated (Contributor+) Arbitrary Gallery Management

Description

The Image Photo Gallery Final Tiles Grid plugin for WordPress is vulnerable to unauthorized access and modification of data due to missing capability checks on multiple AJAX actions in all versions up to, and including, 3.6.9. This makes it possible for authenticated attackers, with Contributor-level access and above, to view, create, modify, clone, delete, and reassign ownership of galleries created by other users, including administrators.
