      "title": "Apache Storm Worker: Unauthenticated Remote Memory Exhaustion in the Worker Messaging Decoder",
      "summary": "Description\n\nThe worker's Netty message decoder is installed ahead of the SASL authentication handlers in the pipeline\nand acts on frames before any authentication has taken place. It allocated buffers sized from a\nlength field carried in the frame, so a single frame from an unauthenticated peer able to reach a worker\nslot port could drive a large allocation.\n\n`storm.messaging.netty.authentication` defaults to false, and the decoder runs before the handler that\nenforces it in any case, so no credentials are required. The attacker needs only TCP reachability to a\nworker port.\n\nThe effect of a single frame at the default 768 MB worker heap has not been measured to distinguish\nsustained worker loss from transient garbage-collection pressure. The severity assigned to this advisory\nreflects the more conservative reading; consumers who require a precise figure should test against their own\nworker heap configuration.\n\nMitigation\n\nUpgrade to 3.1.0, where frames are decoded only after the handshake completes.\n\nUsers who cannot upgrade immediately should ensure that worker slot ports are reachable only from within the\ncluster, as the security model already recommends, and should enable\n`storm.messaging.netty.authentication` where the deployment permits it.\n\nCredit\n\nThe ASF -- found using Claude agents to study the security of open-source projects, validated and reported by Apache Storm.",
