CVE-2026-67403Network attack vector

Cross-tenant administrative access via tenant identifier

Published Sep 9, 2026 · Updated Sep 9, 2026

Improper authorization in Sage AR Automation allows remote authenticated users to access other tenants' administrative resources. Cash Collect's API accepts a valid, non-predictable tenant identifier without confirming that it belongs to the caller's tenant. A valid account and another tenant's identifier are required, exposing administrative resources across the tenant-isolation boundary.
