CVE-2026-108867

Description

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SystemApiController getUserRoleSetById handler that allows any authenticated user to read other users' role assignments. Low-privileged attackers can supply an arbitrary userId parameter to retrieve assigned role codes and identify administrator accounts without the system:user:queryUserRole permission.
