Quick assessment

Affected
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 XSS）漏洞。该漏洞出现在所有 2.4.3 及更早版本中，原因是用户名字段（'user_name'）在输入时未充分进行数据清理（sanitization），且在输出时未正确转义。这使得未经身份验证的攻击者能够在网页中注入任意恶意脚本，当其他用户访问被注入恶意脚本的页面时，脚本将自动执行。 用于在保存时进行过滤的清理函数 对此类攻击向量无效，因为攻击者可构造仅使用未加引号的 HTML 属性语法的有效载荷，其中仅包含空格、字母数字字符以

Vulnerability Title
Mang Board <= 2.4.3 - Unauthenticated Stored Cross-Site Scripting via 'user_name' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'user_name' parameter in all versions up to, and including, 2.4.3 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. The save-time sanitizer mbw_htmlspecialchars2() is ineffective against this vector because the exploit payload relies solely on unquoted HTML attribute syntax using only spaces, alphanumerics, and characters such as =, parentheses, and dots — none of which are escaped.
