daphne before 4.2.2 reconstructs a raw HTTP request from Twisted's parsed headers and feeds it to autobahn for WebSocket handshake processing. Twisted does not treat \x0b, \x0c, \x1c, \x1d, \x1e, or \x85 as header line separators, but autobahn decodes header values to str and calls splitlines(). An attacker can exploit this parser differential to inject additional headers into the ASGI scope passed to the application. daphne now rejects requests with these bytes in any header value with a 400 response.
A flaw was found in daphne. This vulnerability arises from a parser differential where daphne reconstructs HTTP requests from Twisted's headers, but Twisted and autobahn handle certain header line separators differently. An attacker can exploit this to inject additional headers into the ASGI (Asynchronous Server Gateway Interface) scope, potentially leading to information disclosure.
