What is CVE-2025-13619?
CVE-2025-13619 is a critical vulnerability in CMSSuperHeroes Flex Store Users, published on 20 Dec 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Flex Store Users plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.1.0. This is due to the 'fsUserHandle::signup' and the 'fsSellerRole::add_role_seller' functions not restricting what user roles a user can register with. This makes it possible for unauthenticated attackers to supply the 'administrator' role during registration and gain administrator access to the site. Note: The vulnerability can be exploited with the 'fs_type' parameter if the Flex Store Seller plugin is also activated.
Weakness: CWE-269
