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.

在 0.9.2.8 版本之前的"Advanced Custom Fields: Extended"WordPress 插件以及"Advanced Custom Fields: Extended PRO"WordPress 插件中，其前端表单模块在“授权请求”阶段与“执行请求”阶段之间，未能一致地解析"update-user"操作的目标。这导致未认证访客能够绕过保护管理员账户的安全措施，接管站点管理员账户，并获得该账户的有效会话。利用此漏洞需要站点发布两个独立的前端表单配置，且这两个配置的目标均映射到由访客提交的值。

Vulnerability Title
Advanced Custom Fields: Extended 0.9.2.7 - Unauthenticated Administrator Account Takeover via Front-End User Update Action
Source: CVE Program / CVE List V5
Vulnerability Description
The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not resolve the target of the update-user action in its front-end Forms module consistently between the stage that authorises the request and the stage that carries it out, which allows unauthenticated visitors to bypass the guard protecting administrator accounts, take over the site administrator's account and be issued a valid session for it. Exploitation requires the site to publish two separate front-end form configurations whose targets are mapped to visitor-submitted values.
