Description
CoreShop through 2026.2.2 contains a missing authorization vulnerability that allows low-privileged backend users to list permission-restricted resources because ResourceController listAction skips the isGrantedOr403() check. Authenticated Pimcore users lacking resource permissions can request the generated list routes to enumerate payment providers, carriers, price rules, stores, and tax rules including ids, names, and identifiers.
