🎯 What:
Fixed a Cross-Site Scripting (XSS) vulnerability in the dashboard console component (dashboard/src/components/nv-console.ts). Log messages were being directly rendered to the DOM using .innerHTML without any sanitization.

⚠️ Risk:
If any unsanitized user input or unvalidated external data from the transport/WebSocket layer were printed to the dashboard logs, it could be executed as arbitrary JavaScript in the user's browser, leading to session hijacking, data exfiltration, or unauthorized actions within the dashboard context.

🛡️ Solution:

  • Added the dompurify library and its corresponding TypeScript typings to the dashboard dependencies.
  • Wrapped the l.msg interpolation inside DOMPurify.sanitize() prior to assignment to .innerHTML.
  • Verified compilation and build pipelines successfully complete.

Mitigated a Cross-Site Scripting (XSS) vulnerability in `dashboard/src/components/nv-console.ts` where unescaped `consoleLines` messages were directly appended via `.innerHTML`.
Added `dompurify` to sanitize log contents before rendering them, preventing malicious script execution in the client browser.
