The AJAX handler verifies a nonce but does not check user capabilities. This makes it possible for authenticated attackers with Subscriber-level access and above to modify plugin settings and inject malicious scripts that execute when administrators access the plugin settings page or when any user visits the frontend."}], "lastModified": "2026-06-17T10:44:23.670", "sourceIdentifier": "security@wordfence.com"}
