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.
AI Analysis
Technical Summary
The vulnerability in the WooCommerce WordPress plugin before version 1.1.3 arises because the registration form does not validate that the form referenced during registration is legitimate. Instead, it reads the permitted-role allow-list from an attacker-controlled post. Consequently, any user able to create a post with Contributor or higher privileges can exploit this to register a new account with any role, including Administrator, enabling full site compromise. This issue is a regression or incomplete fix of CVE-2026-54807.
Potential Impact
An attacker with Contributor or higher privileges can escalate privileges by registering new accounts with arbitrary roles, including Administrator. This can lead to full site takeover, compromising the integrity and security of the affected WordPress site running the vulnerable WooCommerce plugin.
Mitigation Recommendations
A fix is available in WooCommerce plugin version 1.1.3 or later. Users should upgrade to version 1.1.3 or above to remediate this vulnerability. Until then, restrict post creation privileges to trusted users only. Patch status is not explicitly confirmed in the provided data, but the version 1.1.3 is indicated as the fixed version.
