## Technical details

The vulnerability is a privilege escalation flaw (CWE-269) in the front-end user insertion functionality of Advanced Custom Fields: Extended versions 0.9.2.2 through 0.9.2.6. The plugin does not adequately validate or restrict the role parameter submitted through user registration forms, and safeguards intended to block assignment of privileged roles are incomplete. An unauthenticated attacker can directly submit a request to the vulnerable user form with an elevated role (such as administrator) and bypass the insufficient validation, gaining immediate administrative access to the WordPress installation. The fix is available in version 0.9.2.7 and later.
