CVE-2026-65105 is a missing-authentication vulnerability in the inference-server setup of NVIDIA NemoClaw for Linux, affecting versions 0 through 0.0.25. NemoClaw exposes its local Ollama inference backend on all network interfaces to permit connectivity from the OpenShell container. This configuration can disable Ollama's Host-header validation, allowing a malicious website to use DNS rebinding to access the unauthenticated API through a victim's browser. Unauthorized API access can disclose model information, disrupt inference services, and modify model chat templates. Template modifications can persistently inject hidden instructions beneath agent-level system prompts, influencing subsequent conversations.

A high-severity DNS-rebinding-driven vulnerability in NVIDIA NemoClaw that exposes an unauthenticated Ollama API after NemoClaw binds Ollama to 0.0.0.0:11434. A malicious webpage can access and modify the local Ollama service, including persistently poisoning model chat templates.
A vulnerability in NVIDIA NemoClaw that can allow a malicious web page to take control of a local Ollama model server and implant hidden instructions in the model chat template that persist across subsequent conversations.
A vulnerability in Nvidia NemoClaw's local AI-agent infrastructure that enables a malicious website to use DNS rebinding to bypass origin checks and reach Ollama's unauthenticated local API. Successful exploitation can give an attacker control of the local model server, enabling model enumeration, public-key theft, model/system-prompt poisoning, insecure-code generation, and conversation-data exfiltration.
A high-severity CVSS 8.1 vulnerability that may permit remote unauthenticated access to an inference service.
