## Description

The Gmedia Photo Gallery plugin for WordPress is vulnerable to Cross-Site Request Forgery via the 'module_preset_restore_original' action of the Gmedia Galleries admin page in all versions up to, and including, 1.25.1, due to missing nonce validation and no check on the term the 'preset_default' parameter points to. This makes it possible for unauthenticated attackers to delete any Gmedia term (module presets, galleries, albums, categories or tags), together with its linked WordPress post, via a forged request. The attacker has to trick a site administrator, or another user granted the Gmedia gallery management capability, into performing an action such as clicking on a link.
