CVE-2024-47526Public exploitNetwork attack vector

Session script execution via unescaped template name

Published Oct 1, 2024 · Updated Oct 2, 2024

Self-XSS in LibreNMS before 24.9.0 allows remote authenticated users to execute JavaScript through an alert-template name. The alert-template modal appends the raw submitted name to a bootgrid row before the database sanitizer removes tags. High-privileged access and user interaction are required, and execution is confined to the creator's current session because the payload does not persist.
