CVE-2026-73263Public exploitNetwork attack vector

Authenticated command execution via unchecked kubeconfig cmd-path

Published Aug 12, 2026 · Updated Aug 12, 2026

Command injection in Prowler before 5.36.0 allows remote authenticated users to execute arbitrary commands on shared workers. The kubeconfig validator checks only exec blocks, so a legacy gcp auth-provider cmd-path reaches kubernetes-python and is passed to subprocess.Popen during a provider connection test. Default self-registration supplies the required tenant access, and successful execution runs as the prowler user within the multi-tenant worker.
