CVE-2026-93088Network attack vectorHinoki check available

Remote code execution via unauthenticated pickle loading

Published Sep 22, 2026 · Updated Sep 22, 2026

Unsafe deserialization in SGLang 0.5.11 through 0.5.14 allows remote attackers to execute arbitrary code through a ZeroMQ message. DiffusionServer binds an unauthenticated ROUTER socket to a network interface and passes the final multipart frame directly to pickle.loads() without validation. Exposure requires disaggregated-diffusion server mode and network reachability to the scheduler socket; successful exploitation runs code in the server process.
