Short explanation
In versions prior to 0.9.2.8 of the Advanced Custom Fields: Extended plugin, the front‑end Forms module resolves the target of the update‑user action inconsistently between authorization and execution, allowing unauthenticated visitors who publish two separate form configurations to hijack the administrator account and obtain a valid session.
Compromise of the administrator account gives an attacker full control over the site, threatening content integrity, settings and data confidentiality.
What should be done?
- Upgrade the plugin to version 0.9.2.8 or later
- Review and restrict front‑end form configurations that allow user updates
- Follow the vendor advisory and apply any released patches
- Monitor for suspicious administrator sessions
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Show the technical text from the sources
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.
