## Technical details

The SysRoleController endpoints for role CRUD operations (add, edit, delete, dataScope) lack @PreAuthorize annotations and do not invoke the checkRoleAllowed function to validate user permissions. An authenticated attacker can POST directly to /system/role and related endpoints to manipulate role definitions. The vulnerability requires prior authentication but allows privilege escalation within the application.
