GHSA-HXP9-W8X3-P566 Autobahn Python permessage-deflate bypasses maxMessagePayloadSize after inflation

Summary Autobahn Python enforces maxMessagePayloadSize against the compressed WebSocket frame length before permessage-deflate inflation, then delivers the inflated message to application callbacks without a second size check. A client frame that is only 22 compressed bytes can inflate to 4096...
