CVE-2026-76227
MediumCVSS 5.5Summary
Renovate versions from 42.68.1 before 42.96.3 (and from 42.68.1 before 43.4.4), including corresponding Docker images (renovate/renovate, mend/renovate-ce, renovate-ee-server, renovate-ee-worker >=13.3.0 <13.6.0), fail to restrict environment variables to an allowlist when spawning child processes. As a result, child processes (e.g. npm install, postUpgradeTasks, postUpdateOptions) gain full access to all environment variables of the Renovate process, allowing insider or outside attackers to exfiltrate secrets accessible to the Renovate deployment.
Risk Assessment
Risk of sensitive data leakage, such as tokens, passwords, and API keys, which could be used for further attacks on the infrastructure.
Recommendation
Upgrade Renovate to version 42.96.3 or later (or 43.4.4 for the newer line) and corresponding Docker images to versions containing the fix.
