- Summary
- daphne: Unauthenticated attackers can cause excessive memory consumption by sending arbitrarily large WebSocket messages/frames
- Details
-
daphne before 4.2.2 did not pass maxFramePayloadSize or maxMessagePayloadSize to Autobahn's WebSocketServerFactory. Because Autobahn defaults both values to 0 (unlimited), an unauthenticated remote attacker could send arbitrarily large WebSocket messages or frames, causing excessive memory consumption and a denial of service.
