Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-94.

Summary

SGLang allows unauthenticated pickle deserialization through /update_weights_from_tensor when no auth keys are configured, and the SafeUnpickler policy can be bypassed because builtins.import and builtins.getattr are resolvable, enabling code execution via pickle REDUCE.
