RabbitMQ Java client has frame-level OOM: Math.min(maxInboundMessageBodySize, 0) defeats frame size enforcement

Vulnerability In AMQConnection.java line 435-436, after Connection.Tune negotiation, the frame-max limit is set via: java frameHandler.setFrameMax Math.minthis.maxInboundMessageBodySize, frameMax; When frameMax = 0 meaning "unlimited" per AMQP spec, Math.min67108864, 0 = 0. This value is then...

CVE-2026-77403

A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. A malicious or compromised AMQP broker can exploit this by advertising an extremely small frame size during connection negotiation. This can lead to excessive fragmentation of client publications, consuming significant CPU resources...

CVE-2026-44235: Out-of-bounds Read

rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized HEADER or METHOD frame during client login and cause unsigned sizet underflow in amqphandleinput in librabbitmq/amqpconnection.c. The parser subtracts HEADERSIZE, fixed...

CVE-2026-44236: Heap-based Buffer Overflow

rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized connection.tune.framemax value during amqplogin, and rabbitmq-c accepts the value in amqplogininner in librabbitmq/amqpsocket.c. amqptuneconnection in...

CVE-2026-75516

The RabbitMQ Java client (versions prior to 5.34.0 ) contains a logic flaw where AMQConnection.start() computes Math.min(maxInboundMessageBodySize, frameMax) after Connection.Tune negotiation. Since both the client default and AMQP's zero-value frameMax resolve to zero, Utils.framePayloadLimit(in...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service due to synchronous event channel blocking

A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. When the client synchronously sends events to application-provided channels, an unbuffered or full listener channel can cause the client's reader to block. This blockage prevents the processing of critical messages and heartbeats,...
