CVE-2026-76232 renovatebot CVE debrief

Who should care

Organizations using Renovate for dependency management, especially those with high-security requirements, should be aware of this vulnerability and take immediate action to patch or mitigate it. Affected operators, platforms, and security teams should prioritize patching due to the potential for attackers to execute arbitrary commands. Vulnerability management and security teams should review compensating controls for exposed systems while remediation is scheduled and verified. Monitoring and detection teams should check relevant logs for exposed assets that need extra review. Asset inventory management should track exceptions and retest remediated assets, closing the item only after evidence is documented. Rollback and change management processes should be in place to address any issues that arise during remediation. Source tracking and incident response teams should be prepared to respond to potential exploitation attempts. Security teams should also review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Finally, organizations should confirm whether affected product deployments exist in managed environments and assign an owner for follow-up. This should be done through normal change control procedures where exposure is confirmed. Compensating controls should be reviewed for exposed systems while remediation is scheduled and verified. Monitoring, detection, and logs should be checked for exposed assets that need extra review. Exceptions should be tracked, and remediated assets should be retested. The item should only be closed after evidence is documented. Relevant monitoring, detection, and logs should be checked for exposed assets that need extra review.

Technical summary

Renovate versions from 31.51.0 before 40.33.0 contain a command injection vulnerability in the helmv3 manager. The repository parameter is appended to helm registry login commands without proper sanitization, allowing attackers with repository write access to craft malicious Chart.yaml files and execute arbitrary commands on the machine running Renovate. This vulnerability has a high CVSS score of 8.4, indicating a critical severity level.

Defensive priority

Organizations using Renovate versions from 31.51.0 before 40.33.0 should prioritize patching due to the high CVSS score of 8.4 and the potential for attackers with repository write access to execute arbitrary commands.

Recommended defensive actions

• Patch Renovate to version 40.33.0 or later
• Restrict repository write access to trusted users
• Monitor for suspicious Chart.yaml file changes
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
