Technical details

The PUT /sys/user/doUpdateDepartInfo endpoint in JeecgBoot lacks @RequiresPermissions authorization checks, relying only on JWT authentication. An authenticated attacker can supply an arbitrary department ID to rename departments, change their parent, and reassign or remove department heads without ownership or tenant validation. The vulnerability requires valid JWT credentials but no additional preconditions.
