Technical Analysis
CVE-2026-80467 is a privilege escalation vulnerability in the Advanced Custom Fields: Extended WordPress plugin prior to version 0.9.2.7. The plugin does not properly restrict the roles that can be assigned through its front-end user registration forms, allowing attackers to submit arbitrary roles including privileged ones. The incomplete safeguard enables unauthenticated users to create accounts with elevated privileges and escalate to administrator, violating proper privilege management (CWE-269).
Potential Impact
Successful exploitation allows unauthenticated attackers to register accounts with elevated privileges and escalate to administrator, resulting in full control over the affected WordPress site. This compromises confidentiality, integrity, and availability of the site and its data.
Mitigation Recommendations
No official fix or patch is currently available for this vulnerability. Users should monitor the vendor advisory for updates and apply the official fix once released. Until then, consider disabling front-end user registration or restricting access to the affected plugin functionality to trusted users only.
