CVE-2021-4236 Information

Description

Web Sockets do not execute any AuthenticateMethod methods which may be set leading to a nil pointer dereference if the returned UserData pointer is assumed to be non-nil or authentication bypass. This issue only affects WebSockets with an AuthenticateMethod hook. Request handlers that do not explicitly use WebSockets are not vulnerable.
