CVE-2024-47226Public exploitNetwork attack vector

Stored XSS via unsanitized top-banner rendering

Published Sep 22, 2024 · Updated Feb 11, 2025

Stored XSS in NetBox 4.1.0 Configuration History allows remote authenticated users to inject script through the top-banner field. The Add action at /core/config-revisions/ stores arbitrary JavaScript or HTML in Top banner and renders it in other users' browsers. Authenticated configuration access and a victim viewing the banner are required; the claim is disputed because the field intentionally accepts unsanitized HTML.
