Summary
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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
