Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion in ValueReader table and array parsing. An attacker can crash the client JVM by sending a deeply nested AMQP field value, such as a connection.start frame containing recursively nested tables or arrays. The issue lives in src/main/java/com/rabbitmq/client/impl/ValueReader.java, where readTable() and readArray() recurse through readFieldValue() without any nesting limit. A malicious AMQP peer can trigger a StackOverflowError, killing the client’s I/O thread and causing a denial of service.
