Descriptions

An issue in WooCommerce Payments plugin for WordPress (versions 5.6.1 and lower) allows an unauthenticated attacker to send requests on behalf of an elevated user, like administrator. This allows a remote, unauthenticated attacker to gain admin access on a site that has the affected version of the plugin activated.

The WooCommerce Payments plugin is vulnerable to authentication bypass via the determine_current_user_for_platform_checkout function. This allows unauthenticated attackers to impersonate arbitrary users and perform some actions as the impersonated user, which can lead to site takeover.

WooCommerce-Payments plugin for Wordpress versions 4.8, 4.8.2, 4.9, 4.9.1, 5.0, 5.0.4, 5.1, 5.1.3, 5.2, 5.2.2, 5.3, 5.3.1, 5.4, 5.4.1, 5.5, 5.5.2, and 5.6, 5.6.2 contain an authentication bypass by specifying a valid user ID number within the X-WCPAY-PLATFORM-CHECKOUT-USER header. With this authentication bypass, a user can then use the API to create a new user with administrative privileges on the target WordPress site IF the user ID selected corresponds to an administrator account.
