FKIE_CVE-2026-3835

Vulnerability from fkie_nvd - Published: 2026-08-13 06:17 - Updated: 2026-08-14 19:09
Severity
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
The Prevent Direct Access – Protect WordPress Files plugin for WordPress is vulnerable to unauthorized access of protected files due to insufficient token validation in the `get_advance_file_by_url()` method in all versions up to, and including, 2.8.8.8 The method uses a SQL `LIKE` operator for token lookup without escaping wildcard characters via `$wpdb->esc_like()`. This makes it possible for unauthenticated attackers to bypass the private token requirement by supplying SQL wildcard characters (such as `%`) as the token value, matching any record in the plugin's file table and downloading any protected file.
