CVE-2021-20541Network attack vector

Unauthenticated sensitive-information disclosure via HTTP GET requests

Published Aug 2, 2021 · Updated Sep 16, 2024

Information disclosure in IBM Cloud Pak for Security 1.7.1.0 and earlier allows remote attackers to read sensitive data via HTTP GET requests. IBM identifies HTTP GET request handling as the exposure path but has not published the affected endpoint, field, or authorization failure. No authentication or user interaction is required, and successful requests reveal sensitive information useful for further attacks.
