What is CVE-2026-93088?

The SGLang multimodal generation runtime is exposed to arbitrary code execution through its disaggregated-diffusion orchestrator, which binds an unauthenticated ZeroMQ ROUTER socket to a network interface. This flaw allows an attacker to exploit the system by sending multipart messages that are processed without any validation, leading to unsafe operations with pickle.loads(). As a result, unauthorized users can execute code remotely, posing serious security risks to the integrity and confidentiality of the system.

Affected Version(s)
