Comment 13 Jason Shepherd 2016-11-18 01:24:06 UTC

Our initial analysis of JBoss Fuse 6 showed that it was using a vulnerable version of resteasy. However after further analysis we discovered that it's being used by the Fabic8, Support Webapp feature, which a Restful webservice client, so is not affected by this issue.
