FKIE_CVE-2026-8095

Vulnerability from fkie_nvd - Published: 2026-06-28 00:16 - Updated: 2026-06-29 18:40
Severity
8.1 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
Summary
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.
