CVE intelligence and bounded remediation

CVE-2022-42268 — Omniverse Kit contains a vulnerability in the reference applications Create, Audio2Face, Isaac Sim, View, Code, and Machinima

High CVSS 7.8

Omniverse Kit contains a vulnerability in the reference applications Create, Audio2Face, Isaac Sim, View, Code, and Machinima. These applications allow executable Python code to be embedded in Universal Scene Description (USD) files to customize all aspects of a scene. If a user opens a USD file that contains embedded Python code in one of these applications, the embedded Python code automatically runs with the privileges of the user who opened the file. As a result, an unprivileged remote attacker could craft a USD file containing malicious Python code and persuade a local user to open the file, which may lead to information disclosure, data tampering, and denial of service.

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
