No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Xerte Online Toolkits versions 3.15 and earlier contain an information disclosure vulnerability that allows unauthenticated attackers to retrieve the full server-side filesystem path of the application root. Attackers can send a GET request to the /setup page to access the exposed root_path value rendered in the HTML response, which enables exploitation of path-dependent vulnerabilities such as relative path traversal in connector.php.
