Overview
@budibase/server is a Budibase Web Server
Affected versions of this package are vulnerable to Symlink Attack via the processPWAZip process. An attacker can access sensitive files on the server by uploading a crafted zip archive containing symbolic links that point to arbitrary files, which are then read and served back through the asset-fetch endpoint. This is only exploitable if the attacker has workspace-builder permissions on at least one app.
