Improper Restriction of XML External Entity Reference vulnerability in Apache SIS.

It is possible to write XML files in such a way that, when parsed by Apache SIS, an XML file reveals to the attacker the content of a local file on the server running Apache SIS. This vulnerability impacts the following SIS services:
