CVE-2026-4401

Description

The Download Monitor plugin for WordPress is vulnerable to Cross-Site Request Forgery in the `actions_handler()` and `bulk_actions_handler()` methods in `class-dlm-downloads-path.php` in all versions up to, and including, 5.1.10. This is due to missing nonce verification on these functions. This makes it possible for unauthenticated attackers to delete, disable, or enable approved download paths via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
