CVE-2026-9736Network attack vector

Unauthenticated log injection via unneutralized special elements

Published Sep 3, 2026 · Updated Sep 5, 2026

Log injection in IBM Netezza Software 11.3.0.3 through Interim Fix 002 allows remote attackers to insert forged log data. The affected log-writing path records attacker-controlled special elements without neutralizing them, allowing crafted input to alter log entry boundaries. No authentication or user interaction is required; the established consequence is log integrity loss, and IBM has not identified the specific input field or logging function.
