Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An XML injection vulnerability in the Large Scale VPN (LSVPN) functionality of Palo Alto Networks PAN-OS® software enables an unauthenticated attacker with network access to inject malicious XML content, potentially leading to information disclosure or corruption of internal LSVPN satellite data. Panorama, Cloud NGFW, and Prisma® Access are not impacted by this vulnerability.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A critical XML injection vulnerability exists in Palo Alto Networks PAN-OS Large Scale VPN (LSVPN) functionality. An unauthenticated attacker with network access can inject malicious XML content into the LSVPN service, potentially exposing sensitive information or corrupting internal LSVPN satellite data.

MitigationApply available PAN-OS patches for CVE-2026-0284 immediately and restrict network access to LSVPN management interfaces to untrusted networks until the patch is deployed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify PAN-OS version
    Run 'show system info' in the PAN-OS CLI or check the Dashboard in the web interface to locate the PAN-OS version field
    Affected if The installed version falls within any of these ranges: 10.2.0-10.2.6, 10.2.8-10.2.9, 10.2.11-10.2.12, 10.2.14-10.2.15, 10.2.17-10.2.18, 11.1.0-11.1.3, or 11.1.8-11.1.9
  2. Confirm LSVPN is configured
    In the PAN-OS web interface, navigate to Network > Large Scale VPN or use 'show vpn lsvpn' CLI command to check for any LSVPN satellite or gateway configurations
    Affected if An LSVPN configuration exists with at least one satellite or gateway defined
  3. Verify management interface exposure
    Check network accessibility of the interface handling LSVPN management traffic by reviewing 'show interface' and testing connectivity from untrusted networks using ping or telnet to the management IP
    Affected if The LSVPN management interface is reachable from untrusted or external networks
  4. Review XML processing logs
    Use 'tail follow yes mp-log lsvpn.log' in the CLI to monitor real-time LSVPN logs for unusual XML content or parsing errors
    Affected if Malformed or unexpected XML entries appear in the LSVPN logs indicating injection attempts

Your environment is affected if you run a vulnerable PAN-OS version within the listed ranges AND have LSVPN enabled with management interfaces accessible from untrusted networks.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to 10.2.7 / 10.2.10 / 10.2.13 or later
Fixed in 10.2.710.2.1010.2.13
Interim mitigation

Apply available PAN-OS patches for CVE-2026-0284 immediately and restrict network access to LSVPN management interfaces to untrusted networks until the patch is deployed.

Recommended fix High confidence

Upgrade to PAN-OS 10.2.16 or later (or the latest 10.2.x stable release)

  1. 1. Confirm the current PAN-OS version by navigating to Device > Support or using 'show system info' in the CLI
  2. 2. Schedule a maintenance window for the upgrade (PAN-OS upgrades require a reboot)
  3. 3. Download the appropriate PAN-OS upgrade image from the Palo Alto Networks Customer Support Portal
  4. 4. If using a physical appliance, upload the image via Dashboard > Software or via CLI: request system software install <filename>
  5. 5. If using Panorama-managed devices, push the upgrade via Panorama > Device Deployment > Software
  6. 6. After installation, verify the new version is running: show system info
  7. 7. Test LSVPN functionality to confirm the upgrade did not break existing tunnel configurations
  8. 8. Review logs to confirm the XML injection vulnerability is no longer exploitable
Caveat PAN-OS upgrades may require configuration adjustments; review release notes for any deprecated features or behavioral changes before upgrading
