Security Advisory
CVE-2026-4068
CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
The Add Custom Fields to Media plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.3. This is due to missing nonce validation on the field deletion functionality in the admin display template. The plugin properly validates a nonce for the add field operation (line 24-36), but the delete field operation (lines 38-49) processes the $_GET[delete] parameter and calls update_option() without any nonce verification. This makes it possible for unauthenticated attackers to delete arbitrary custom media fields via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.
