WordPress · Frontend File Manager Plugin · CVE-2026-8095
**Name of the Vulnerable Software and Affected Versions**
Frontend File Manager Plugin versions prior to 23.7
**Description**
Authenticated users with Subscriber-level access can delete arbitrary files on the server, including sensitive files like wp-config.php, which may lead to a full site takeover. The issue occurs in the `wpfm file meta update` AJAX handler due to a case-sensitive bypass of the `wpfm dir path` parameter sanitization. By providing the parameter as `WPFM DIR PATH` in uppercase, the unset check is evaded, and the value is later normalized to `wpfm dir path` by the `sanitize key()` function during `update post meta()`. This allows the stored file path to be overwritten with an arbitrary filesystem path, which is then passed to the `unlink()` function within `delete file locally()` without directory containment validation.
**Recommendations**
Update to the latest version.
As a temporary mitigation, restrict access to the `wpfm file meta update` AJAX handler for users with Subscriber-level permissions.
