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-2026-75516 RabbitMQ Java client: Frame-level OOM: Math.min(maxInboundMessageBodySize, 0) defeats frame size enforcement

The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.34.0, AMQConnection.start applies Math.minmaxInboundMessageBodySize, frameMax after Connection.Tune negotiation even though AMQP defines frameMax value zero as...

CVE-2026-77403

RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, Connection.openTune in connection.go accepts a server-advertised FrameMax below the AMQP frameMinSize value of 4096 bytes because the connection negotiation loop does not enforce the protocol minimum. A malicious or compromised AMQP...

CVE-2026-77403

RabbitMQ amqp091-go is a Go AMQP 0.9.1 client library. Prior to version 1.13.0, the Connection.openTune function in connection.go fails to enforce the AMQP protocol minimum frame size (frameMinSize of 4096 bytes), accepting a server-advertised FrameMax below this threshold. A malicious or comprom...
