Summary
JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to remove user group members by calling DELETE /sys/user/deleteUserGroupBatch. Attackers can supply any groupId and comma-separated userIds to delete sys_ugroup_user rows without permission or tenant checks, tampering with administrator-maintained groups.
