CVE-2020-4562Network attack vector

Information disclosure via unrestricted cross-window messaging

Published Apr 26, 2021 · Updated Sep 16, 2024

Information disclosure in IBM Planning Analytics 2.0 allows remote attackers to read sensitive data through documentation frames. The documentation-frame messaging logic permits cross-window communication with an unrestricted target origin, delivering data outside the intended origin boundary. No authentication or user interaction is required, and the reported effect is limited to confidentiality rather than data modification or service interruption.
