Description
SGLang through 0.5.22 in prefill/decode disaggregation mode contains a server-side request forgery vulnerability that allows unauthenticated attackers to trigger outbound requests via client-supplied bootstrap_host and bootstrap_port fields. Attackers sending crafted requests to the Decode worker's /generate endpoint can probe internal hosts and ports and block the shared scheduler loop, delaying other inference requests.
