Until a fix is available, restrict access to the affected endpoints to trusted users only and monitor for unauthorized access. Implement additional access controls or custom permission checks if possible.
Description
Guns through 8.3.5 contains an information disclosure vulnerability in SysUserController where /sysUser/detail and /sysUser/page endpoints omit requiredPermission configuration, causing the permission interceptor to skip RBAC validation for authenticated users. Attackers with any valid login token can retrieve sensitive user information including account names, real names, email addresses, phone numbers, last login IPs, and role assignments for all users in the system.
