CVE-2025-36040Network attack vector

Unauthorized actions via insufficient session expiration

Published Jul 30, 2025 · Updated Jul 31, 2025

Insufficient session expiration in IBM Aspera Faspex 5.0.0 through 5.0.12.1 allows remote authenticated users to perform unauthorized actions. IBM attributes the flaw to client-side enforcement of a server-side security mechanism but does not identify the affected endpoint or session-state check. A valid authenticated session is required, and the published impact is limited to unauthorized state changes without data disclosure or service interruption.
