Resolved MinorIncident Report
Summary AI Generated
Cloud Agent for Windows versions 6.5 and 6.6 on the EU03, AU01, and CA01 platforms generated false-positive vulnerability findings for QIDs that evaluate file versions read from disk, with no actual change to host security posture. The incident lasted 7 minutes before Qualys reverted the published agent version on affected platforms back to 6.4 to prevent further auto-upgrades. A permanent fix will be delivered in Cloud Agent for Windows 6.7.2, with rollout beginning August 24, 2026.
