Palo Alto Networks Cloud NGFW: denial of service
Medium6.6CVE-2026-0287 · Published Jul 9, 2026 · updated Aug 11, 2026
Multiple denial of service vulnerabilities in Palo Alto Networks PAN-OS® software allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition by sending specially crafted network traffic to or through a dataplane interface. Repeated attempts to trigger this condition result in the firewall entering maintenance mode. Panorama is not impacted by these vulnerabilities.
