 "title": "Frontend Admin by DynamiApps <= 3.29.13 - Unauthenticated Privilege Escalation via Form Field Keys",
 "description": "The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Privilege Escalation via submitted form field keys in all versions up to, and including, 3.29.13. This is due to the form submission handler accepting values for fields that are not part of the submitted form, including fields of other forms, ACF field groups and other pages, and to field names being used as meta keys without excluding reserved keys such as the user capabilities and user level meta. This makes it possible for unauthenticated attackers, on sites with a publicly available form that saves user data, such as a registration form, to save values for fields defined elsewhere on the site and, where a field that resolves on the site has a name matching a reserved key, to grant an account the administrator role.",
