A denial-of-service vulnerability was discovered in skupper-router within the AMQP field parser. The flaw is caused by unbounded recursion when processing deeply nested or specially crafted AMQP messages, leading to a stack overflow. An attacker who can send messages to the router can trigger this crash. Exploitation requires the attacker to possess a valid x.509 certificate signed by the Red Hat Service Interconnect network's certificate authority. Successful exploitation results in the skupper-router process crashing, terminating all active connections and preventing new traffic from being routed through the affected node.
