Attackers can exploit a networking vulnerability in NVIDIA's OpenClaw tool to gain unauthenticated access to the local model server via the Ollama API, enabling persistent corruption of AI agents.

This attack vector poses significant risks to organizations deploying NVIDIA's AI tools in production environments.
Two critical authentication bypass vulnerabilities (CVE-2026-61979 and CVE-2026-15981), both rated CVSS 9.8, in the miniOrange SAML 2.0 Single Sign On WordPress plugin are being actively exploited in the wild.
