CVE-2025-66359Network attack vector

Script execution via unvalidated unescaped web input

Published Nov 27, 2025 · Updated Nov 28, 2025

Cross-site scripting in Logpoint SIEM before 7.7.0 allows remote authenticated users to execute scripts through crafted application input. Multiple components accept insufficiently validated input and render it without output escaping, but Logpoint has not named the components or fields. Low-privileged access is required, and exploitation runs scripts in the affected web context with confidentiality, integrity, and availability impact.
