Assigner: VulnCheck

Description
Renovate before 44.14.7 contains a command injection vulnerability in the Maven Wrapper manager that allows attackers to execute arbitrary commands by specifying a malicious distributionType parameter in maven-wrapper.properties. Attackers can inject shell commands through unescaped distributionType values to achieve remote code execution when Renovate processes Maven Wrapper updates in binarySource=docker mode.

Executive Summary

CVE-2026-88889 is a command injection vulnerability in Renovate versions before 44.14.7. It occurs in the Maven Wrapper manager when processing updates in Docker mode. Attackers can inject malicious commands via the distributionType parameter in maven-wrapper.properties, leading to arbitrary code execution.

Detection Guidance

Check for Renovate versions before 44.14.7 by running: renovate --version. Inspect maven-wrapper.properties files in repositories for malicious distributionType values like script ; cp /etc/passwd /tmp/passwd. Monitor Docker containers running Renovate for unexpected command execution or file modifications.

Impact Analysis

This vulnerability allows attackers to execute arbitrary commands on systems running vulnerable Renovate instances. This could lead to unauthorized access, data theft, system compromise, or disruption of services. The impact depends on the privileges of the Renovate user.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements and HIPAA's security rules. Organizations may face compliance penalties if exploited, as it compromises confidentiality and integrity of protected information.

Mitigation Strategies

Upgrade Renovate to version 44.14.7 or later immediately. Disable the Maven Wrapper manager if not required. Avoid using binarySource=docker mode for Maven Wrapper updates. Review and remove any suspicious distributionType entries in maven-wrapper.properties files.
