CVE-2026-8095— Frontend File Manager Plugin <= 23.6 - Authenticated (Subscriber+) Arbitrary File Deletion

Frontend File Manager Plugin <= 23.6 - Authenticated (Subscriber+) Arbitrary File Deletion

The Frontend File Manager Plugin plugin for WordPress is vulnerable to Authenticated Arbitrary File Deletion in versions up to and including 23.6. This is due to a case-sensitive bypass of the wpfm_dir_path parameter sanitization in the wpfm_file_meta_update AJAX handler, where supplying WPFM_DIR_PATH in uppercase evades the unset check and is normalized to wpfm_dir_path by sanitize_key() during update_post_meta(), allowing an attacker to overwrite the stored file path with an arbitrary filesystem path that is then passed directly to unlink() in delete_file_locally() without any directory containment validation. This makes it possible for authenticated attackers with Subscriber-level access to delete arbitrary files on the server, including sensitive files such as wp-config.php, potentially leading to full site takeover.

N-Media Frontend File Manager Plugin 输入验证错误漏洞

N-Media Frontend File Manager Plugin是N-Media个人开发者的一款前端文件管理器插件。 N-Media Frontend File Manager Plugin 23.6及之前版本存在输入验证错误漏洞，该漏洞源于在wpfm_file_meta_update AJAX处理器中对wpfm_dir_path参数清理存在大小写绕过，导致攻击者覆盖存储文件路径，并直接传递给delete_file_locally()中的unlink()函数，可能导致经过身份验证的攻击者删除服务器
