CVE-2026-0316 · Severity: info · Published 2026-10-14

PAN-OS is the operating system for Palo Alto Networks firewalls and security platforms that protect enterprise networks. A malicious administrator can inject and store malicious JavaScript code through the management web interface that executes when other administrators access the system, potentially leading to account takeover or unauthorized configuration changes. The risk is substantially lower if the management interface is restricted to trusted internal IP addresses only.

**Am I affected by CVE-2026-0316?** Check whether you run Palo Alto Networks PAN-OS or Palo Alto Networks Panorama at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in PAN-OS 12.2.4, 12.1.10-h2, 11.2.16, 11.1.16-h3

Restrict access to the management interface to only trusted internal IP addresses and deploy a jump box as the single point of access to the management interface, as recommended in Palo Alto Networks best practice deployment guidelines.

## Technical details

A stored cross-site scripting (CWE-79) vulnerability in PAN-OS web interface allows an authenticated administrator to persist JavaScript payloads that execute in the browsers of other users accessing the interface. The attack requires high-privilege administrative credentials and user interaction (passive) to trigger; no special configuration is needed to be vulnerable. An attacker with admin access gains the ability to execute arbitrary client-side actions on other administrators' sessions.

## Affected products

- Palo Alto Networks PAN-OS 12.2.0–12.2.3, 12.1.2–12.1.10-h1, 11.2.0–11.2.15, 11.1.0–11.1.16-h2
- Palo Alto Networks Panorama 12.2.0–12.2.3, 12.1.2–12.1.10-h1, 11.2.0–11.2.15, 11.1.0–11.1.16-h2
