CVE-2021-4359 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N

The Frontend File Manager plugin for WordPress is vulnerable to Unauthenticated Arbitrary Post Deletion in versions up to, and including, 18.2. This is due to lacking authentication protections and lacking a security nonce on the wpfm_delete_file AJAX action. This makes it possible for unauthenticated attackers to delete any posts and pages on the site.
