Doc Text:
A flaw was found in Renovate. This arbitrary command injection vulnerability exists within the kustomize manager, where user-provided chart names are not properly sanitized before being used in helm pull commands. An attacker with write access to a repository can exploit this by crafting malicious kustomization.yaml files with specially designed chart names. This allows them to execute arbitrary commands on the Renovate host machine, leading to arbitrary code execution.

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.
