Cortex XDR Agent: Local Administrator can disable the agent on Windows

MonitorCVSS 6.7CVE-2026-0232Apr 8, 2026
Palo Alto Networks
IT in OT - Palo Alto firewalls are commonly deployed at IT/OT network boundaries
Summary

A protection mechanism in the Palo Alto Networks Cortex XDR agent on Windows can be disabled by a local Windows administrator. This vulnerability allows malware or an attacker with local admin access to remove endpoint detection and response monitoring, preventing detection of subsequent malicious activity on the system.

What this means
What could happen
A local Windows administrator could disable the Cortex XDR agent, removing endpoint detection and response capabilities from the system. This would allow malware to run and execute malicious activity without security monitoring or alerts.
Who's at risk
This affects any organization running Cortex XDR Agent on Windows systems, particularly those with sensitive OT/ICS networks or critical infrastructure where endpoint detection is essential for detecting unauthorized access or malware compromise.
How it could be exploited
An attacker with local administrative access to a Windows system (either through compromised credentials, malware already running with admin privileges, or lateral movement from another compromised system) can disable the Cortex XDR agent using local Windows administrative commands or tools, bypassing the protection mechanism that normally prevents this action.
