CVE-2026-75977— Mang Board WP <= 2.3.7 - Authenticated (Subscriber+) Privilege Escalation to Forged Authentication Cookie

Quick assessment

Affected
kitae-park Mang Board WP
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 插件在所有不超过且包括 2.3.7 的版本中，存在通过伪造身份验证 Cookie 导致的缺失授权漏洞。该漏洞源于 函数中 HMAC 生成逻辑存在缺陷：当 WordPress 用户已登录时，该函数使用了当前用户的身份信息，而非 Cookie 中的用户名参数；同时， 函数对身份验证 Cookie 的验证不够充分。这使得拥有订阅者及以上权限的已认证攻击者能够伪造管理员身份验证 Cookie，并将管理员密码修改为任意值，从而实现对整个网站的完全接管。

Vulnerability Title
Mang Board WP <= 2.3.7 - Authenticated (Subscriber+) Privilege Escalation to Forged Authentication Cookie
Source: CVE Program / CVE List V5
Vulnerability Description
The Mang Board WP plugin for WordPress is vulnerable to Missing Authorization via Authentication Cookie Forgery in all versions up to, and including, 2.3.7. This is due to flawed HMAC generation in the mbw_get_hash_key() function that uses the current user's identity instead of the cookie username parameter when a WordPress user is logged in, combined with insufficient validation in mbw_validate_auth_cookie(). This makes it possible for authenticated attackers, with subscriber-level access and above, to forge administrator authentication cookies and change administrator passwords to achieve complete site takeover.
