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.
Impact Depending on implementation, a denial-of-service or privilege escalation vulnerability may occur in software that uses the github.com/ecnepsnai/web package with Web Sockets that have an AuthenticateMethod. The AuthenticateMethod is not called, and UserData will be nil in request methods. Attempts to read the UserData may result in a panic. This issue only affects web sockets where an AuthenticateMethod is supplied to the handle options. Users who do not use web …
