LibreNMS: Reflected XSS via Proxmox instance/vmid GET parameters injected into document.title JavaScript assignment

### Summary `LegacyController.php:75` writes the page title into a `document.title` JS assignment using string interpolation. `apps/proxmox.inc.php` pushes `$vars['instance']` and `$vars['vmid']` (GET params, only `strip_tags()` applied) directly into `$pagetitle`. A single quote terminates the JS string, executing arbitrary script. ### Details ```php // LegacyController.php:75 $html .= "<script>\ndocument.title = '$title';\n</script>"; // proxmox.inc.php:38,42 $pagetitle[] = $instance; //
