CVE-2023-22644Network attack vector

Authenticated code execution via forged JWTs

Published Sep 20, 2023 · Updated Apr 7, 2025

Authentication weakness in NeuVector 5.2.1 and earlier allows remote authenticated users to execute code through forged JWTs. Manager and API authentication trust JWTs signed with a built-in reusable certificate, allowing its recovered signing key to mint accepted tokens. A valid low-privileged account and network access to the Manager or REST API are required; forged authorization can reach custom compliance-script execution.
