Description
JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to delete category dictionary entries via DELETE /sys/category/deleteBatch. Attackers can obtain node ids from the unguarded rootList and childList endpoints and submit them to recursively delete entire sys_category subtrees, breaking dependent forms and dictionary fields.
