An improper handing of overflow in the UTF-8 decoder with supplementary characters can lead to an infinite loop in the decoder causing a Denial of Service (CVE-2018-1336). The defaults settings for the CORS filter are insecure and enable supportsCredentials for all origins. It is expected that users of the CORS filter will have configured it appropriately for their environment rather than using it in the default configuration. Therefore, it is expected that most users will not be impacted by this issue (CVE-2018-8014). The host name verification when using TLS with the WebSocket client was missing. It is now enabled by default (CVE-2018-8034). When the default servlet returned a redirect to a directory (e.g. redirecting to /foo/ when the user requested /foo) a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice (CVE-2018-11784).
