CVE-2021-20422Network attack vector

Unauthenticated sensitive data disclosure from memory

Published Jul 13, 2021 · Updated Sep 16, 2024

Information disclosure in IBM Cloud Pak for Applications 4.3 allows remote attackers to read sensitive data from process memory. IBM identifies the exposed locus only as data stored in memory and has not published the request, endpoint, or memory-handling operation that returns it. No authentication or user interaction is required; the documented consequence is read-only exposure, with no integrity or availability impact.
