CVE-2025-36039Network attack vector

Authenticated unauthorized actions via client-side security enforcement

Published Jul 30, 2025 · Updated Jul 31, 2025

Improper authorization in IBM Aspera Faspex 5.0.0 through 5.0.12.1 allows remote authenticated users to perform unauthorized actions. The web client enforces a server-side security decision that the server does not independently validate; IBM has not identified the affected request or authorization check. Low-privileged network access is required, and the documented consequence is unauthorized modification without reported disclosure or service interruption.
