Unauthenticated Remote Code Execution Vulnerability in NVIDIA SIL GEN3C Product

CVE-2026-53805

What is CVE-2026-53805?

The GEN3C product from NVIDIA's Spatial Intelligence Lab is affected by a serious vulnerability that allows unauthenticated remote code execution. This flaw resides in the inference API server, specifically in the /request-inference and /seed-model endpoints, which utilize Python's pickle.loads() for deserializing raw HTTP request bodies. Due to the lack of robust authentication and input validation, an attacker can exploit this vulnerability by sending a specially crafted payload containing a reduce gadget, ultimately gaining remote code execution capabilities during the inference process.
