Credential disclosure via undisclosed Web UI script injection

Published May 27, 2026 · Updated May 27, 2026

Cross-site scripting in IBM Cognos Analytics and Cognos Transformer allows remote authenticated users to disclose session credentials. IBM has not disclosed the affected Web UI field, page, or handler, but states that it accepts embedded JavaScript and renders it within a trusted session. Exploitation requires low-privileged access and user interaction; executed script can alter interface behavior and expose credentials, with no reported availability impact.
