Publication date: 2026-09-10

Last updated on: 2026-09-10

Assigner: VulnCheck

Description
Renovate before 44.14.7 contains a command injection vulnerability in the gomod manager when processing unescaped depName parameters in import-path update commands with binarySource=docker mode. Attackers can inject shell metacharacters through malicious dependency names to execute arbitrary commands as the Renovate user during Go module major version updates with postUpdateOptions gomodUpdateImportPaths enabled.

Executive Summary

This is a command injection vulnerability in Renovate versions before 44.14.7. It occurs in the gomod manager when processing depName parameters during import-path updates with binarySource set to docker mode. Attackers can inject shell metacharacters through malicious dependency names to execute arbitrary commands as the Renovate user.

Detection Guidance

To detect this vulnerability, check the Renovate version installed on your system using the command 'renovate --version'. If the version is below 44.14.7, the system is vulnerable. Additionally, inspect configuration files for 'binarySource=docker' and 'postUpdateOptions' with 'gomodUpdateImportPaths' enabled.

Impact Analysis

An attacker could execute 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 attack requires a malicious dependency name, which is typically invalid in Go, making exploitation unlikely except in insider scenarios.

Compliance Impact

This vulnerability could lead to unauthorized code execution, potentially causing data breaches. This may result in non-compliance with GDPR (data protection), HIPAA (health data security), or other regulations requiring strict access controls and audit trails.

Mitigation Strategies

Immediately update Renovate to version 44.14.7 or later. Remove or disable the 'binarySource=docker' mode in configurations. Review and sanitize dependency names to prevent injection. Monitor for unusual activity in Renovate logs.
