WordPress 插件 DevKit Pro 在所有不超过（含）2.3.0 的版本中均存在导致管理员账户被劫持的身份验证绕过漏洞。该漏洞源于 处理逻辑盲目信任由攻击者控制的 Cookie，将其视为特权身份。具体而言， 函数错误地检查由 Cookie 所标识用户是否具备 权限，而非通过 对实际请求者进行权限验证；同时，只要该 Cookie 存在，系统就会通过 向包括未认证访客在内的所有访问者公开呈现“切换回原用户”表单及一个与会话绑定且有效的 nonce 值。这使得未认证的攻击者能够将 Cookie 设置为任意管理

Vulnerability Title
DevKit Pro <= 2.3.0 - Unauthenticated Authentication Bypass to Administrator Account Takeover via 'original_user_id' Cookie in Frontend Revert Switch Flow
Source: CVE Program / CVE List V5
Vulnerability Description
The DevKit Pro plugin for WordPress is vulnerable to Authentication Bypass Leading to Administrator Account Takeover in all versions up to, and including, 2.3.0 This is due to the `revert_switch` handler trusting the attacker-controlled `original_user_id` cookie as the privileged identity: `verify_nonce_and_capability()` incorrectly checks the `manage_options` capability on the user identified by the cookie rather than on the actual requester via `current_user_can()`, while the switch-back form and a valid session-bound nonce are emitted publicly via `wp_footer` to any visitor — including unauthenticated users — whenever that cookie is present. This makes it possible for unauthenticated attackers to set the `original_user_id` cookie to any administrator's user ID, collect the rendered nonce, and POST it back to the `revert_switch` handler, causing `wp_set_auth_cookie()` to be called with the administrator's ID and granting the attacker a full administrator-level authenticated session and complete site takeover.
