CVE-2025-36034Network attack vector

Sensitive-data disclosure via cleartext API requests

Published Jun 26, 2025 · Updated Aug 26, 2025

Cleartext transmission in IBM InfoSphere DataStage Flow Designer 11.7 allows man-in-the-middle attackers to read sensitive user information. The affected API places sensitive user information into requests in clear text rather than protecting the values against interception. Exploitation requires an authenticated API exchange and a man-in-the-middle network position; the reported impact is limited to disclosure.
