summary: Panic or authentication bypass in github.com/ecnepsnai/web
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.
