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.

Affected Version(s)

GEN3C 0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
