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.

Vulnerability Description
WordPress Prevent Direct Access是WordPress基金会开源的一款保护网站文件不被直接访问的插件。 WordPress Prevent Direct Access 2.8.8.8及之前版本存在授权问题漏洞，该漏洞源于get_advance_file_by_url()方法中token验证不足，未通过$wpdb->esc_like()转义SQL LIKE操作符中的通配符，可能导致未经身份验证的攻击者绕过私有token要求并下载任意受保护文件。
