SGLang through 0.5.22 with the Mooncake disaggregation backend accepts unauthenticated decode registration messages on the Prefill rank ZMQ PULL socket, allowing denial of service. Network-adjacent attackers can send many registrations with unique mooncake session id values and large nested-buffer frames to exhaust Prefill memory until the scheduler is OOM-killed.
