CVE-2026-84099

IDB Ecommerce (wpStoreCart 5) <= 5.0.7 - Unauthenticated PHP Object Injection via bundled wpsc-membership-pro paypal.php

The wpstorecart WordPress plugin through 5.0.7 does not prevent direct, unauthenticated access to a bundled add-on that deserializes user-supplied input without restricting the permitted classes, allowing unauthenticated attackers to inject arbitrary PHP objects, which may be escalated further when a suitable gadget chain is present on the site.
