CVE-2024-51454Network attack vector

Session hijacking via unvalidated Host headers

Published Jun 22, 2026 · Updated Jun 22, 2026

HTTP header injection in IBM Engineering Workflow Management 7.0.2, 7.0.3, and 7.1 allows remote attackers to hijack sessions. Host header processing accepts attacker-controlled values without proper validation, enabling cross-site scripting, cache poisoning, and session hijacking. No authentication or user interaction is required; affected ranges end at 7.0.2 Interim Fix 035, 7.0.3 Interim Fix 017, and 7.1 Interim Fix 004.
