Publication date: 2026-07-09

Last updated on: 2026-07-13

Assigner: Palo Alto Networks, Inc.

Description
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.

Executive Summary

CVE-2026-0287 is a medium-severity vulnerability in Palo Alto Networks PAN-OS software that allows an unauthenticated attacker with network access to cause a denial of service (DoS) condition.

The attacker can send specially crafted network traffic to or through a dataplane interface, which can repeatedly trigger the vulnerability and cause the firewall to enter maintenance mode.

This issue affects multiple PAN-OS versions including 12.1, 11.2, 11.1, and 10.2, as well as Prisma Access and Cloud NGFW services.

The vulnerability is classified under CWE-754 (Improper Check for Unusual or Exceptional Conditions) and CAPEC-153 (Input Data Manipulation).

Detection Guidance

There is no specific information provided about detection methods or commands to identify this vulnerability on your network or system.

Impact Analysis

This vulnerability can impact you by allowing an unauthenticated attacker to cause a denial of service (DoS) on your Palo Alto Networks firewall.

Repeated exploitation attempts can force the firewall into maintenance mode, potentially disrupting network security and availability.

This disruption could lead to downtime or degraded network protection until the device is restored from maintenance mode.

Prisma Access and Cloud NGFW services have some built-in resilience to mitigate this risk, but Prisma Access still requires authenticated and restricted network access.

Compliance Impact

The provided information does not specify how this vulnerability affects compliance with common standards and regulations such as GDPR or HIPAA.

Mitigation Strategies

To mitigate this vulnerability, users are advised to upgrade to fixed versions of PAN-OS or Prisma Access.

Palo Alto Networks will automatically upgrade customers during scheduled maintenance cycles, but on-demand upgrades can be requested through support.

No workarounds are available, so upgrading is the primary mitigation step.
