WordPress More Fields Plugin 2.1 contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized actions by disabling CSRF token validation. Attackers can craft malicious web pages that trick logged-in administrators into adding or deleting custom fields and boxes on the Write/Edit page via POST and GET requests to the options-general.php endpoint.
