Aias00 opened a new issue, #6848: URL: https://github.com/apache/shenyu/issues/6848
## Description The SUBACK grant list is built by hard-coding `MqttQoS.AT_MOST_ONCE.value()` for every topic, never reading `topicSub.qualityOfService()`. ## Location - `shenyu-protocol/shenyu-protocol-mqtt/src/main/java/org/apache/shenyu/protocol/mqtt/Subscribe.java:90-94` (line 93 hard-codes `AT_MOST_ONCE.value()`) ## Impact A client subscribing at QoS 1 or 2 is told it was granted QoS 0 and (see H-27) will only ever receive QoS 0 delivery. Violates MQTT-3.8.4/3.9. ## Suggested fix `qos.add(topicSub.qualityOfService().value())` (after the FAILURE filter). -- This is an automated message from the Apache Git Service.
