Official description

The Abandoned Cart Lite for WooCommerce plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 5.14.2. This is due to insufficient encryption on the user being supplied during the abandoned cart link decode through the plugin. This allows unauthenticated attackers to log in as users who have abandoned the cart, who are typically customers. Further security hardening was introduced in version 5.15.1 that ensures sites are no longer vulnerable through historical check-out links, and additional hardening was introduced in version 5.15.2 that ensured null key values wouldn't permit the authentication bypass.

The underlying weakness: Authentication Bypass Using an Alternate Path or Channel

The product requires authentication, but the product has an alternate path or channel that does not require authentication.

How developers prevent this class of flaw

  • Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
