CVE-2026-108872: JeecgBoot authorization bypass in batchEditUsers handler

CVE-2026-108872 · Severity: medium · CVSS 4.3 · Published 2026-10-11

JeecgBoot is an open-source enterprise application development platform. An authenticated user can send requests to the batchEditUsers API to reassign any user—including administrators—to different departments without proper permission checks. This allows low-privilege attackers to manipulate organizational structure and user roles, potentially gaining elevated access.

Technologies: JeecgBoot. Vendors: JeecgBoot.

Technical details

The SysUserController's batchEditUsers handler (PUT /sys/user/batchEditUsers) lacks @RequiresPermissions annotation, allowing any authenticated user to move arbitrary users between departments and overwrite their positions. The endpoint accepts userIds, selected departments, and post IDs in the request body and directly modifies sys_user_depart database relations without verifying the caller's authorization. An attacker with valid JWT credentials can exploit this to reorganize users, reassign administrators, or escalate privileges by manipulating department-level permissions.
