The Registration Form for WooCommerce WordPress plugin before 1.1.3 does not validate that the form referenced during registration is a legitimate registration form, reading the permitted-role allow-list from an arbitrary attacker-controlled post instead. A user able to create a post (Contributor and above) can therefore register a new account with an arbitrary role, including Administrator, leading to full site takeover. This is an incomplete fix of CVE-2026-54807.
