  "details": "## Summary\nThe max body size was enforced to patch CVE-2023-46120, but even though that limit still works, the frame size itself still exceeds the given max size. \n\n## Root cause\nThe Java client records the AMQP 0-9-1 `frame_max` negotiated during connection tuning, but the socket inbound frame reader continues to validate broker-controlled payload lengths against the much larger `maxInboundMessageBodySize` limit. A broker peer can therefore send a method frame whose payload is larger than the negotiated `frame_max`, have it allocated and decoded, and complete the connection handshake instead of being rejected as a protocol violation.\n\n*Reported by Team Atlanta.*",
