SGLang contains a DoS vulnerability caused by missing input validation for AUXDATA ZeroMQ control messages in the Decode worker, which enables an unauthenticated remote attacker with network reachability to the Decode control PULL socket to terminate the Decode control thread and cause a denial of service against the target server.

SGLang's multimodal generation runtime is vulnerable to unauthenticated arbitrary code execution because the disaggregated-diffusion orchestrator's DiffusionServer binds an unauthenticated ZeroMQ ROUTER socket to a network interface and passes the final frame of received multipart messages directly to pickle.loads() before any validation occurs.

SGLang contains an SSRF and local file read in the multimodal generation endpoint /v1/chat/completions due to unsanitized imageurl, allowing access to internal metadata, secrets, and services.
