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 插件在所有 2.4.5 及更早版本中，由于输入清理和输出转义不足，其 参数存在存储型跨站脚本（Stored XSS）漏洞。这使得拥有“贡献者”级别及以上权限的已认证攻击者能够在页面中注入任意 Web 脚本；当任何用户访问被注入的页面时，这些脚本将被执行。由于恶意载荷不包含尖括号（< 和 >）， 函数在保存时会保留短代码原样，导致恶意属性值在文章提交后仍能存活，并在任何查看者的浏览器中触发执行——包括正在预览待发布文章的管理员。

Vulnerability Title
Mang Board <= 2.4.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'align' Shortcode Attribute
Source: CVE Program / CVE List V5
Vulnerability Description
The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'align' parameter in all versions up to, and including, 2.4.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Because the payload contains no angle brackets, wp_kses_post leaves the shortcode intact on save, allowing the malicious attribute value to survive post submission and fire in any viewer's browser — including an administrator previewing a pending post.
