Unauthenticated Administrator access via unrestricted role registration
Published Dec 20, 2025 · Updated Dec 20, 2025
Privilege escalation in CMSSuperHeroes Flex Store Users 1.1.0 and earlier allows remote attackers to register administrator accounts. The fsUserHandle::signup and fsSellerRole::add_role_seller functions accept a requested role without restricting registration to permitted roles. Exploitation through the fs_type parameter requires Flex Store Seller to be active; successful registration grants full site administration.
