CVE-2026-69220

Name	CVE-2026-69220
Description	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 for AMQP table type F and AMQP array type A values without a nesting-depth limit. A malicious AMQP server or network intermediary can send approximately 580 nested table levels in the pre-authentication connection.start frame, fitting within the default 131072-byte frame maximum, to trigger StackOverflowError. The error terminates the client input processing thread and causes denial of service. This issue is fixed in version 5.33.1.
