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-2026-75516

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 via unbounded body buffer allocation

A flaw was found in RabbitMQ amqp091-go. A malicious or compromised broker can send an extreme declared message body size to a client. This causes the client to attempt an excessively large memory allocation without proper size capping, leading to memory exhaustion and termination of the client...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service via signed-to-unsigned integer casting

A flaw was found in RabbitMQ amqp091-go. The Channel.Qos function in channel.go incorrectly handles negative integer values for prefetchCount and prefetchSize, casting them to large unsigned integers. This allows an application that processes untrusted Quality of Service QoS configuration to...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service via AMQP frame size negotiation

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...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Plaintext Credential Exposure via Exported PLAIN Authentication Fields

A flaw was found in RabbitMQ amqp091-go, a Go client for AMQP 0.9.1. This vulnerability allows plaintext credentials to be exposed. After a successful PLAIN authentication handshake, the client retains passwords in an unencrypted format within its connection configuration. Local code with access ...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service via Malicious AMQP Field Length

A flaw was found in RabbitMQ amqp091-go. A malicious or compromised broker can send a specially crafted AMQP Advanced Message Queuing Protocol message with a malformed field length. This can cause an integer overflow, leading to a runtime panic in the client process. Consequently, the client...

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,...
