CVE-2025-33118Network attack vector

Credential disclosure via stored Web UI scripts

Published Aug 1, 2025 · Updated Aug 1, 2025

Stored cross-site scripting in IBM QRadar SIEM 7.5 through 7.5.0 Update Pack 12 allows remote authenticated users to disclose credentials. The Web UI stores attacker-supplied JavaScript and later executes it within a trusted session; IBM has not identified the affected field, page, or handler. An authenticated account is required to plant the script; public materials do not identify the affected workflow or whether another user must view it.
