CVE-2026-53805 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. NVIDIA Spatial Intelligence Lab's (SIL) GEN3C contains an unauthenticated remote code execution vulnerability in the inference API server where the /request-inference and /seed-model endpoints deserialize raw HTTP request bodies using Python's pickle.loads() without authentication or input validation. Attackers can supply a crafted payload containing a __reduce__ gadget to the inference API port to achieve remote code execution as the inference process.. EPSS estimates a 0.69% chance of exploitation in the next 30 days.
