CVE-2026-76231
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
