Executive Summary

This vulnerability is a command injection flaw in Renovate versions 31.51.0 to 40.33.0. It occurs in the helmv3 manager where the repository parameter is added to helm registry login commands without proper sanitization. Attackers with repository write access can craft malicious Chart.yaml files to execute arbitrary commands on the machine running Renovate.

Detection Guidance

To detect this vulnerability, check the installed version of Renovate. If it is between 31.51.0 and 40.33.0, the system is vulnerable. Run: npm list -g renovate or check package.json for Renovate version.

Impact Analysis

If exploited, this vulnerability allows attackers to run arbitrary commands on the machine running Renovate. This could lead to unauthorized access, data theft, system compromise, or disruption of services. The impact depends on the privileges of the Renovate process and the attacker's goals.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by allowing arbitrary command execution on the Renovate execution machine. Unauthorized command execution may lead to unauthorized access to sensitive data, violating confidentiality and integrity requirements of these regulations. Attackers with repository write access could exfiltrate, modify, or delete sensitive information, which would be a direct violation of GDPR's data protection principles and HIPAA's security rules.

Mitigation Strategies

Upgrade Renovate to version 40.33.0 or later immediately. Remove write access to repositories scanned by Renovate if not required. Monitor for suspicious activity in Renovate logs.
