CVE-2026-109188 · Severity: medium · CVSS 4.3 · Published 2026-10-12

jshERP is an enterprise resource planning (ERP) system used to manage business data across a tenant organization. A flaw in the authorization controls allows any authenticated user with low-level privileges to create organization-wide master data such as products, accounts, and departments by directly calling API endpoints. This could enable a disgruntled employee or compromised account to inject unauthorized business records into the system.

## Technical details

The vulnerability is a missing authorization check in multiple data creation and import endpoints (/account/add, /material/add, /material/importExcel, etc.) that fail to verify whether the authenticated user has permission to create tenant-wide master data. An authenticated attacker can craft POST requests to these endpoints to directly create settlement accounts, inventory items with initial stock, departments, and system dictionary entries without role-based validation, affecting all users in the tenant.
