Add Custom Fields To Media
Monthly
The Add Custom Fields to Media WordPress plugin versions up to 2.0.3 contains a Cross-Site Request Forgery (CSRF) vulnerability in the field deletion functionality that allows unauthenticated attackers to delete arbitrary custom media fields. The vulnerability exists because the plugin validates nonces for the 'add field' operation but fails to validate nonces on the 'delete field' operation, which processes the $_GET['delete'] parameter directly. An attacker can exploit this by tricking a site administrator into clicking a malicious link, resulting in unauthorized deletion of custom media field configurations with no authentication required beyond social engineering.
