No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Renovate versions from 32.135.0 before 40.33.0 contain a command injection vulnerability in the hermit manager where user-provided dependency names are appended to install and uninstall commands without proper sanitization. Attackers with repository write access can provide maliciously named hermit dependencies to execute arbitrary commands on the machine running Renovate.
