jshERP through 3.6 contains an authorization bypass vulnerability in the userBusiness CRUD endpoints that allows authenticated users to create, modify, or delete authorization-relation rows without privilege checks. Attackers can manipulate user-role mappings and access controls to escalate privileges, strip access from other accounts, or modify role-function relationships for any user in the tenant.
