Executive Summary

This is a command injection vulnerability in Renovate versions before 44.14.7. It occurs in the Mix manager when processing private dependencies with unescaped organization parameters. Attackers can inject shell metacharacters through malicious package names to execute arbitrary commands as the Renovate user when running in binarySource=docker mode.

Detection Guidance

Check Renovate version with 'renovate --version'. If version is below 44.14.7, the system is vulnerable. Inspect logs for Mix manager commands with suspicious package names containing shell metacharacters.

Impact Analysis

An attacker could exploit this to run arbitrary commands on your system with the privileges of the Renovate user. This could lead to data theft, system compromise, or further network infiltration. The impact is higher if Renovate runs in docker mode as the commands execute with elevated privileges.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR's integrity and confidentiality requirements or HIPAA's security rules for protected health information. Organizations may face compliance penalties if exploited.

Mitigation Strategies

Upgrade Renovate to version 44.14.7 or later immediately. Disable binarySource=docker mode if used, as it is deprecated and will be removed in future versions.
