CVE-2025-13619: CWE-269 Improper Privilege Management in CMSSuperHeroes Flex Store Users
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.
AI Analysis
Technical Summary
CVE-2025-13619 is a privilege escalation vulnerability in the CMSSuperHeroes Flex Store Users WordPress plugin. The issue arises because the 'fsUserHandle::signup' and 'fsSellerRole::add_role_seller' functions do not properly restrict user role assignment during registration. This allows unauthenticated attackers to specify the 'administrator' role, gaining full administrative access to the WordPress site. The vulnerability is exploitable when the Flex Store Seller plugin is also enabled, leveraging the 'fs_type' parameter. The CVSS 3.1 base score is 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting network attack vector, no privileges or user interaction required, and full impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation grants an unauthenticated attacker administrator-level access to the affected WordPress site. This compromises the entire site’s confidentiality, integrity, and availability, allowing full control over site content, user data, and configuration.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to disable or remove the Flex Store Users plugin, especially if the Flex Store Seller plugin is also active, to prevent exploitation. Monitor vendor channels for updates and apply patches promptly once released.
