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

The Weave server API allows remote users to fetch files from a specific directory, but due to a lack of input validation, it is possible to traverse and leak arbitrary files remotely. In various common scenarios, this allows a low-privileged user to assume the role of the server admin.
