CVE-2026-86793

9.8 criticalEPSS 0.8%

Critical (9.8). EPSS 0.8% chance of exploitation in the next 30 days.

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.
