Description Sam Fowler 2018-06-14 02:12:43 UTC
Eclipse Vert.x before version 3.5.2 does not properly neutralize CR and LF characters in HTTP request before return responses. A remote attacker could exploit this to inject abritrary HTTP response headers to potentially mount cross-site scripting and cache poisoning attacks.

While the affected artifact is being shipped in Fuse 6.3 via camel-vertx component, the vulnerable code is not being used, therefore Fuse 6.3 is not affected.
