CVE-2026-108882 · Severity: medium · CVSS 5.4 · Published 2026-10-11

JeecgBoot is a rapid-development framework used to build enterprise Java applications. A flaw in the position management component allows any authenticated user to remove other users from their assigned positions without proper permission checks. This enables privilege escalation or workforce disruption, as attackers could detach users from critical organizational roles.

## Technical details

The SysPositionController removeUserPosition handler lacks authorization validation, permitting any authenticated attacker to send DELETE requests with arbitrary userIds and positionId parameters to delete sys_user_position records. The vulnerability requires prior authentication but not elevated privileges; successful exploitation results in unauthorized modification of user-position assignments with no audit trail.
