Summary
youlai-boot through 2.21.1 contains a missing authorization vulnerability that allows authenticated users to assign arbitrary menu and button permissions to roles via PUT /api/v1/roles/{roleId}/menus. Low-privileged users such as the GUEST test account can grant all permissions to their own role, refreshing the Redis permission cache to gain administrator-equivalent access.
