What is CVE-2025-13619?

The Flex Store Users plugin for WordPress, prior to version 1.1.0, contains a vulnerability that allows attackers to escalate privileges. This occurs due to improper role restrictions in the 'fsUserHandle::signup' and 'fsSellerRole::add_role_seller' functions, enabling unauthenticated users to register with an 'administrator' role. If the Flex Store Seller plugin is also activated, the 'fs_type' parameter can be exploited to facilitate this attack, threatening the security of affected WordPress sites.
