CVE-2026-54085 wazuh CVE debrief

Who should care

Organizations using Wazuh for security monitoring and incident response should be aware of this vulnerability and take steps to mitigate it. Specifically, Wazuh users should review their active response scripts, validate input to these scripts, and implement additional logging and monitoring for suspicious activity. Upgrading to Wazuh version 4.14.7 or later is recommended to prevent argument injection attacks. Security teams should also review their vulnerability management processes to ensure timely application of patches and updates.

Technical summary

In Wazuh versions 4.2.0 through 4.14.6, multiple active response scripts pass attacker-influenced alert fields to privileged system commands without validating their format, allowing argument injection into tools that run as root. This enables injecting additional command arguments, and on Windows the unquoted CreateProcess command-line concatenation in wpopenv() lets a srcip containing spaces add further arguments, while disable-account.c can be abused to lock arbitrary system accounts. The issue is fixed in version 4.14.7, which validates input to prevent such attacks.

Defensive priority

Organizations using Wazuh versions 4.2.0 through 4.14.6 should prioritize upgrading to version 4.14.7 to mitigate argument injection vulnerabilities in active response scripts.

Recommended defensive actions

• Upgrade to Wazuh version 4.14.7 or later
• Review and validate input to active response scripts
• Implement additional logging and monitoring for suspicious activity
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The CVE record indicates that multiple active response scripts in Wazuh versions 4.2.0 through 4.14.6 pass attacker-influenced alert fields to privileged system commands without validating their format, allowing argument injection. The issue is fixed in version 4.14.7. Evidence is limited to the CVE description and NVD entry, which provide high-level details of the vulnerability. Defenders should verify the affected Wazuh versions, review active response scripts for similar vulnerabilities, and monitor for suspicious activity that could indicate exploitation attempts.
