Vulnerability Title
Prevent Direct Access – Protect WordPress Files <= 2.8.8.8 - Unauthenticated Protected File Access
Source: CVE Program / CVE List V5
Vulnerability Description
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.
