## Overview

JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows any authenticated user to permanently delete data dictionaries via the deletePhysic handler of SysDictController. Low-privileged attackers can send DELETE requests to /sys/dict/deletePhysic/{id} to irreversibly remove active dictionaries and all their items, bypassing the recycle bin.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
