JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysPositionController edit handler that allows any authenticated user to modify organizational positions. Low-privileged attackers can obtain position ids from the unguarded list endpoint and send PUT or POST requests to /sys/position/edit to alter position names, codes, and ranks.
