Summary
eladmin through 2.7 contains an authorization bypass vulnerability that allows department-scoped user managers to modify or delete accounts outside their data scope because write handlers skip department checks. Attackers with user:edit or user:del permissions can send PUT or DELETE requests to /api/users with target user ids to disable, reassign, alter, or delete accounts in other departments.
