CVE-2026-88889: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in renovatebot renovate
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.
AI Analysis
Technical Summary
CVE-2026-88889 is an OS command injection vulnerability in renovatebot's Renovate product prior to version 44.14.7. The issue exists in the Maven Wrapper manager component, where the distributionType parameter in the maven-wrapper.properties file is not properly neutralized. Attackers can inject shell commands via this parameter, which are executed when Renovate processes Maven Wrapper updates in binarySource=docker mode, leading to remote code execution. The CVSS 4.0 score is 8.5, indicating high severity. No official patch or remediation level is currently documented, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation allows an attacker with low privileges and no user interaction to execute arbitrary OS commands remotely on the host running Renovate when processing Maven Wrapper updates in docker mode. This can lead to full system compromise or unauthorized control of the Renovate environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid processing Maven Wrapper updates in binarySource=docker mode or sanitize the distributionType parameter to prevent injection. Monitor vendor channels for updates and apply patches promptly once released.
