CVE-2026-2483Network attack vector

Authenticated credential disclosure via Web UI script injection

Published Mar 25, 2026 · Updated Mar 25, 2026

Cross-site scripting in InfoSphere Information Server 11.7.0.0 through 11.7.1.6 allows remote authenticated users to inject JavaScript via the Web UI. IBM states that the Web UI embeds attacker-supplied JavaScript, but does not identify the affected page, parameter, or missing output-neutralization step. Another user must interact with the affected content; execution in that trusted session can disclose credentials and alter Web UI behavior.
