Cross-tenant data access via unchecked customerid
Published Apr 22, 2026 · Updated Apr 22, 2026
Authorization bypass in Augmentt 1.0 allows remote authenticated users to read and alter other tenants' data via crafted requests. The web backend accepts a user-controlled customerid when creating or modifying resources without verifying that the session is authorized for the referenced tenant. A valid user session and another tenant identifier are required; demonstrated consequences include disclosure, resource creation, and configuration changes.
