CWE-22 — Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

This CVE was published Jun 20, 2026 and is one of 18 known issues for this plugin.

Update, patch or deactivate.

Update Simple File List to a release after 6.3.7, or disable and remove it until a fixed version is available.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The Simple File List plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the eeSFL_DeleteFile function in all versions up to, and including, 6.3.7. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The simplefilelist_edit_job AJAX action is registered via wp_ajax_nopriv_, making it accessible without authentication, and the is_admin() guard that would otherwise restrict access is bypassed because is_admin() always returns true for requests to the admin-ajax.php endpoint.
