What is CVE-2026-92461?

yshop-crm versions up to 2.1.3 contain a missing authorization vulnerability in the GET /admin-api/crm/flow/flow-users endpoint. This flaw allows any authenticated back-office user to access sensitive approval workflow data, including the approval chain topology, ordering, and identifiers for approvers, as well as personal details such as login names, nicknames, departments, email addresses, mobile numbers, and last login IP addresses. The lack of proper authorization checks exposes critical information, potentially enabling unauthorized users to exploit the system and compromise user privacy.
