Additionally, an attacker can achieve the same effect by forging the RocketMQ protocol content. \n\nTo prevent these attacks, users are recommended to upgrade to version 5.1.1 or above for using RocketMQ 5.x or 4.9.6 or above for using RocketMQ 4.x .","summary":"Apache RocketMQ NameServer, Broker and Controller components lack permission checks and are reachable from the internet.
