AnalysisAIv1 – Sep 15, 2026

Stored cross-site scripting in IBM Cognos Analytics 12.0.4 through 12.0.4 FP2 and 12.1.0 through 12.1.3 FP1 allows any authenticated non-privileged user to embed JavaScript in their own given name or surname profile fields. The payload is later rendered without encoding in the administrative user-account management panel, so the script executes in an administrator's browser session when that account's permissions are reviewed, potentially exposing the administrator's session cookies. The issue is rated CVSS 5.4 (medium) and a vendor patch is available; no public exploit code or CISA KEV entry was present in the provided intelligence, so active exploitation is not confirmed.

DescriptionCVE.org

IBM Cognos Analytics 12.1.0 through 12.1.3 FP1, and 12.0.4 through 12.0.4 FP2 allows a non-privileged user to edit their given name and surname to include malicious JavaScript code. When an administrator later accesses the user account management panel and views that user's permissions, the malicious JavaScript code is executed. This could result in the cookies from the administrator being compromised.
