Entity (XXE) expansion. A remote attacker able to submit an SAXSource
containing an XXE declaration could use this flaw to read files accessible
to the user running the application server, and potentially perform other
more advanced XXE attacks. (CVE-2015-0263)

It was found that Apache Camel performed XML External Entity (XXE)
expansion when evaluating invalid XML Strings or invalid XML GenericFile

server, and potentially perform other more advanced XXE attacks.
(CVE-2015-0264)
