CVE-2026-44546

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...

Allocation of Resources Without Limits or Throttling

Overview daphne is a Django ASGI HTTP/WebSocket server Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of enforced limits on WebSocket message and frame sizes in the WebSocketServerFactory process. An attacker can exhaust...

GHSA-XH68-HFP5-5X5M daphne: WebSocket handshake header smuggling through autobahn splitlines() mishandling of non-standard line separators

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...

GHSA-RRC9-MX66-FFCM daphne: Unauthenticated attackers can cause excessive memory consumption by sending arbitrarily large WebSocket messages/frames

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...
