Fixed In Version:	XStream 1.4.9	Doc Type:	Bug Fix
Doc Text:	It was found that several XML parsers used by XStream had default settings that would expand entity references. A remote, unauthenticated attacker could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks.	Story Points:	---

Description Andrej Nemec 2016-03-29 07:29:18 UTC

XStream (x-stream.github.io) is a Java library to marshal Java objects into 
XML and back. For this purpose it supports a lot of different XML parsers. 
Some of those can also process external entities which was enabled by 
default.

An attacker could therefore provide manipulated XML as input to access data 
on the file system, see
