CVE-2026-0316: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Palo Alto Networks Cloud NGFW
Description
CVE-2026-0316 is a stored cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software affecting PA-Series, VM-Series firewalls, and Panorama devices. It allows a malicious authenticated administrator to store or execute JavaScript payloads via the web interface. The risk is reduced if management access is restricted to trusted internal IPs as recommended by Palo Alto Networks. Cloud NGFW and Prisma Access are not affected. The vulnerability has a low severity score and no known exploits in the wild.

Technical Analysis
This vulnerability (CVE-2026-0316) is a stored XSS issue in PAN-OS software that enables an authenticated administrator to inject and execute JavaScript code through the management web interface. It affects PA-Series and VM-Series firewalls and Panorama (virtual and M-Series) running specific PAN-OS versions. The vulnerability does not impact Palo Alto Networks Cloud NGFW or Prisma Access services. The vendor recommends restricting management interface access to trusted internal IP addresses to minimize risk.
Potential Impact
An authenticated administrator could exploit this vulnerability to execute arbitrary JavaScript in the context of the management web interface, potentially leading to session hijacking or other client-side attacks. However, the overall risk is low due to the requirement for authenticated access and the ability to limit management interface exposure to trusted IPs. There are no known exploits in the wild.
Mitigation Recommendations
Restrict management interface access to trusted internal IP addresses as per Palo Alto Networks' best practice guidelines. Since this vulnerability affects on-premises PAN-OS devices and not cloud services, administrators should apply vendor-recommended access controls. Patch status is not explicitly provided; check Palo Alto Networks advisories for updates and fixes.
