## Overview

JeecgBoot 3.9.2 and earlier contains an authorization bypass vulnerability in the SystemApiController component. An authenticated attacker with any valid JWT token can access multiple API endpoints (including queryAllUser, queryUsersByUsernames, queryUserById, and queryUsersByIds) to retrieve sensitive information of all users, including real names, phone numbers, email addresses, employee numbers, and role definitions, due to missing fine-grained permission checks and incomplete data desensitization.

## Remediation

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