  4. ResultAttacker gains control of the service

What happened

NVIDIA NeMo Agent Toolkit has a missing authentication vulnerability (CVSS 10, critical) that can be triggered by an attacker to bypass access controls.

Why it is dangerous: Successful exploitation could lead to code execution, privilege escalation, data tampering, denial of service, and information disclosure. Any deployment exposed to a network where the toolkit accepts requests is at risk.

Are you affected?

You are affected if you run NVIDIA NeMo Agent Toolkit in a version the advisory marks as vulnerable, especially if it is reachable from networks you do not fully trust.

NVIDIA NeMo Agent Toolkit (exact vulnerable versions not stated in the provided material)

What to do

  1. Check the GitHub advisory GHSA-8mjc-3v3w-78r7 for the exact vulnerable and patched versions
  2. Update NeMo Agent Toolkit to the patched version as soon as it is available
  3. Restrict network access to the toolkit so it is not exposed to untrusted users until patched
