## Overview

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysPositionController removeUserPosition handler that allows any authenticated user to remove position members. Low-privileged attackers can send DELETE requests with arbitrary userIds and positionId values to delete sys_user_position rows, detaching users from positions without logging.
