kitae-park Mang Board
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WordPress 的 Mang Board 插件存在存储型跨站脚本（Stored Cross-Site Scripting）漏洞。在所有 2.4.2 及更早版本中，由于对 参数的输入清理和输出转义不足，攻击者可以在网页中注入任意的 Web 脚本，当用户访问被注入的页面时，这些脚本就会执行。 此漏洞可在任何采用默认配置（write_level=0 即允许游客发帖，editor_type=N）的论坛板上被利用，而这些配置是新建论坛板的出厂默认设置。

Vulnerability Title
Mang Board <= 2.4.2 - Unauthenticated Stored Cross-Site Scripting via 'data_type' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'data_type' parameter in all versions up to, and including, 2.4.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable on any board configured with the default write_level=0 (guest posting) and editor_type=N settings, which are the out-of-the-box defaults for newly created boards.
