CVE-2023-38276Network attack vector

Sensitive data disclosure via environment variables

Published Oct 22, 2023 · Updated Sep 11, 2024

Information disclosure in IBM Cognos Dashboards on Cloud Pak for Data 4.7.0 allows remote attackers to read sensitive environment data. IBM has not published the affected endpoint or the operation that exposes environment-variable values. No credentials or user action are required, but unspecified high-complexity conditions gate confidentiality loss that can support further attacks.
