The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.37.0, com.rabbitmq.tools.json.JSONReader.read() fails to terminate when input ends inside a quoted string or a line comment because its string and whitespace scanners do not stop at CharacterIterator.DONE. The default DefaultJsonRpcMapper passes JSON-RPC message bodies to this parser for JsonRpcServer and client replies.
A truncated string causes the parser to append replacement end markers until heap exhaustion, while a line comment without a terminating newline can keep a thread consuming CPU indefinitely, resulting in denial of service. This issue is fixed in version 5.37.0.
