CVE-2026-0281 Palo Alto Networks CVE debrief

CVE-2026-0281 is an information disclosure vulnerability in Palo Alto Networks PAN-OS software. An unauthenticated attacker with network access to the management web interface can obtain web session tokens, requiring a legitimate user to first click on a malicious link. The security risk is minimized by restricting access to the management web interface to only trusted internal IP addresses. The issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series). Cloud NGFW and Prisma Access are not impacted by this vulnerability. System administrators and security teams managing Palo Alto Networks PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series) should be aware of this vulnerability.

Who should care

System administrators and security teams managing Palo Alto Networks PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series) should be aware of this vulnerability and take necessary actions to minimize the security risk.

Technical summary

The vulnerability allows an unauthenticated attacker with network access to the management web interface to obtain web session tokens. This requires a legitimate user to first click on a malicious link provided by the attacker. The issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series). Cloud NGFW and Prisma Access are not impacted. The security risk is minimized by restricting access to the management web interface to only trusted internal IP addresses.

Defensive priority

Medium priority due to the low CVSS score of 2.1 and the requirement for user interaction.

Recommended defensive actions

  • Restrict access to the management web interface to only trusted internal IP addresses
  • Implement network segmentation to limit access to sensitive areas
  • Monitor for suspicious activity and implement incident response plans
  • Keep PAN-OS software up to date with the latest security patches
  • Educate users about the risks of clicking on malicious links
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
