A fix is available — apply it.

Renovate versions from 39.218.0 before 40.33.0 contain an arbitrary command injection vulnerability in the kustomize manager where user-provided chart names are appended to helm pull commands without proper sanitization. Attackers with repository write access can craft malicious kustomization.yaml files with specially crafted chart names to execute arbitrary commands on the Renovate host machine.
