org.jboss.resteasy:resteasy-jaxrs is a JCP specification that provides a Java API for RESTful Web Services over the HTTP protocol.

Affected versions of this package are vulnerable to HTTP Request Smuggling. It was discovered that the CORS Filter did not add an HTTP Vary header indicating that the response varies depending on Origin. This permitted client and server side cache poisoning in some circumstances.
