CVE-2026-0265 remediation guide

Palo Alto Networks Cloud NGFW, PAN-OS, Prisma Access

An authentication bypass vulnerability in Palo Alto Networks PAN-OS® software enables an unauthenticated attacker with network access to bypass authentication controls when Cloud Authentication Service (CAS) is enabled. The risk is higher if CAS is enabled on the management interface and lower when any other login interfaces are used. The risk of this issue is greatly reduced if you secure access to the management web interface by restricting access to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/com...

01

Identify the affected asset

Confirm whether Palo Alto Networks Cloud NGFW, PAN-OS, Prisma Access is installed, record the deployed version and installation path, and identify exposed interfaces.

  • Record the product name, package or appliance identifier, and installed version.
  • Identify internet-facing, administrative, API, and internal access paths.
  • Preserve the pre-change configuration and relevant service logs.
02

Validate the affected-version match

Compare the deployed version with the affected range: >= 12.1.0 < 12.1.7, 12.1.4-h5, >= 11.2.0 < 11.2.12, 11.2.10-h6, 11.2.7-h13, 11.2.4-h17, >= 11.1.0 < 11.1.15, 11.1.13-h5, 11.1.10-h25, 11.1.7-h6, 11.1.6-h32, 11.1.4-h33, >= 10.2.0 < 10.2.18-h6, 10.2.16-h7, 10.2.13-h21, 10.2.10-h36, 10.2.7-h34, < 10.2.7, >= 10.2.8 < 10.2.10, >= 10.2.11 < 10.2.13, >= 10.2.14 < 10.2.16, 10.2.7, 10.2.10, 10.2.13, 10.2.16, 10.2.17, 10.2.18, >= 11.1.0 < 11.1.4, >= 11.1.5 < 11.1.6, >= 11.1.8 < 11.1.10, >= 11.1.11 < 11.1.13, 11.1.4, 11.1.6. Treat incomplete inventory results as unresolved.

03

Prioritize with independent signals

The CVSS severity warrants an early asset and exposure review. Combine this signal with asset criticality, exposure, compensating controls, and business impact.

04

Apply supported remediation

Follow the vendor advisory or supported update path. Current fixed-version status: 10.2.7, 10.2.10, 10.2.13, 10.2.16, 11.1.4, 11.1.6, 11.1.10, 11.1.13, 11.2.4, 11.2.7, 11.2.10, 12.1.4, 12.1.7. Preserve configuration and rollback material before change.

05

Verify the result

Confirm the resulting version, service health, authentication and access paths, monitoring coverage, and relevant security logs.

  • Confirm the expected version and package state.
  • Run a functional health check for critical service paths.
  • Review authentication, error, application, and security monitoring logs.
  • Reassess exposure if the supported fix cannot be applied.

Operational boundary

This page does not replace the vendor advisory, support contract, change-management process, or recovery plan. Do not infer that an asset is unaffected from an incomplete inventory query or a missing fixed-version field.
