Impacted is integrity, and availability. CVE summarizes:

The WP-DownloadManager plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.69 via the 'file' parameter in the file deletion functionality. This is due to insufficient validation of user-supplied file paths, allowing directory traversal sequences. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, which can lead to remote code execution when critical files like wp-config.php are deleted.

The advisory is available at wordfence.com. This vulnerability is handled as CVE-2026-2426. The exploitation is known to be easy. The attack may be launched remotely. The exploitation requires an enhanced level of successful authentication. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
