RabbitMQ Java client ValueReader: Oversized LongString/bytes length triggers OOM via unchecked allocation

Summary ValueReader.readBytes allocates a byte array sized by a wire-declared content length without validating it against actual frame data. A malicious AMQP peer triggers OOM by declaring a 2GB string/bytes field. Vulnerable Code src/main/java/com/rabbitmq/client/impl/ValueReader.java lines...

The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java permits ValueReader.readTable and ValueReader.readArray to call ValueReader.readFieldValue recursively f...

The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java uses ValueReader.readBytes to accept a wire-declared contentLength below Integer.MAXVALUE and allocate a...

CVE-2026-69219

The vulnerability is in ValueReader.readBytes in ValueReader.java of the RabbitMQ Java client prior to 5.33.1: it allocates a byte array based on a wire-declared length before verifying available frame data, allowing a malicious AMQP peer to trigger a ~2 GB allocation and OutOfMemoryError during ...
