CVE-2026-7301 Details
Description
SGLangs multimodal generation runtime scheduler's ROUTER socket binds to 0.0.0.0 by default and contains a sink that calls pickle.loads() on incoming messages, enabling RCE when exposed to the internet.
A remote code execution vulnerability exists in the SGLang multimodal generation runtime scheduler. The issue arises because the ROUTER socket binds to all network interfaces by default and processes incoming messages with pickle.loads(), allowing for remote code execution when the socket is exposed to the internet. This vulnerability affects SGLang versions 0.5.5 and later, specifically when the multimodal runtime is enabled and the scheduler socket is reachable on all interfaces.
