CVE-2025-33137Network attack vector

Authenticated data access via client-side authorization

Published May 22, 2025 · Updated Aug 26, 2025

Authorization bypass in IBM Aspera Faspex 5.0.0 through 5.0.12 allows remote authenticated users to read sensitive data or act as another user. The product trusts client-side security controls without enforcing the same authorization decisions on the server, but IBM has not identified the affected endpoint or request field. A valid account is required; successful requests expose protected information or perform another user's permitted actions, with no documented service interruption.
