Published Jul 28, 2025 · Updated Jul 28, 2025

HTML injection in Informix HQ for IBM Informix Dynamic Server 12.10 and 14.10 allows remote authenticated users to execute browser scripts. The alerting configuration feature accepts HTML scripts in the script Location field and displays them without neutralizing script-related tags. Exploitation requires low-privileged access and user interaction, and IBM states that injected content affects only the attacker's own session.
