PAN-OS Fixes GlobalProtect Source-IP Authorization Bypass
Tech GuruQuick Answer
Validate GlobalProtect gateway exposure and source-IP-based controls, then apply the branch-specific PAN-OS fix. Coordinate Prisma Access maintenance with the vendor and test allowed and denied access.
Confirm Scope And Apply The Supported Remediation
What to do now: Record product, exact running build, service owner, exposure path, relevant configuration and maintenance dependencies. Check Network > GlobalProtect > Gateways and the authorization rules tied to source IP. Valid GlobalProtect credentials are required. Apply the fixed PAN-OS build for each supported branch. Prisma Access 11.2 requires the supported 12.1.10-h4-or-later upgrade; contact support for an earlier cloud maintenance window. Test representative permitted and prohibited VPN access, policy enforcement and high-availability health after the update.

Scope And Authority
| Product scope | PAN-OS GlobalProtect gateways and affected Prisma Access releases |
|---|---|
| Advisory | CVE-2026-0325 |
| CVE | CVE-2026-0325 |
| Authoritative release date | November 11, 2026 at 17:00 UTC, from the vendor RSS entry and CSAF initial release timestamp. |
| Authority revision date | Initial publication on November 11, 2026; no separate material revision. CSAF generation timestamps are not treated as advisory revisions. |
| Affected versions | PAN-OS 12.2, 12.1, 11.2 and 11.1 before the corresponding fixed builds below, with a GlobalProtect gateway enabled. Prisma Access 12.1 before 12.1.10-h4 and Prisma Access 11.2 are affected. Cloud NGFW is unaffected. |
| Fixed version | PAN-OS 12.2.4-h2, 12.1.10-h4, 11.2.16-h2 or 11.1.16-h5, as applicable to the installed branch; Prisma Access 12.1.10-h4 or later |
| CVSS base score | 5.3 (CVSS v4.0 base score) |
| CVSS severity | Medium |
| Exploitation status | Palo Alto Networks states that it is not aware of malicious exploitation of this issue.; no exploitation claim is inferred. |
What Changed
An attacker with valid GlobalProtect credentials can bypass source-IP restrictions and network access controls that depend on those restrictions.
What To Validate Now
- Inventory. Record product, exact running build, service owner, exposure path, relevant configuration and maintenance dependencies.
- Establish applicability. Check Network > GlobalProtect > Gateways and the authorization rules tied to source IP. Valid GlobalProtect credentials are required.
- Remediate. Apply the fixed PAN-OS build for each supported branch. Prisma Access 11.2 requires the supported 12.1.10-h4-or-later upgrade; contact support for an earlier cloud maintenance window.
- Validate. Test representative permitted and prohibited VPN access, policy enforcement and high-availability health after the update.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Vendor exposure-reduction guidance includes DoS policies, country restrictions and IP blocklists; these are not a substitute for the fix. Preserve VPN and firewall policy logs.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.

Vendor Product and Build Matrix
Match each threshold to the corresponding maintenance branch. Multiple fixed builds are alternatives within their own maintenance lines; they are not a single cross-branch version range. Asterisks mark vendor-managed cloud maintenance, which must be confirmed with support.
| Product or branch | Affected builds | Unaffected builds |
|---|---|---|
| Cloud NGFW | None | All |
| PAN-OS 12.2 | < 12.2.4-h2 | >= 12.2.4-h2 |
| PAN-OS 12.1 | < 12.1.10-h4 | >= 12.1.10-h4 |
| PAN-OS 11.2 | < 11.2.16-h2 | >= 11.2.16-h2 |
| PAN-OS 11.1 | < 11.1.16-h5 | >= 11.1.16-h5 |
| Prisma Access 12.1 | < 12.1.10-h4* | >= 12.1.10-h4* |
| Prisma Access 11.2 | All* | None* |
Score Interpretation and First-Party Evidence
Base scores and severities above come from the vendor-hosted JSON. The page also displays threat-adjusted CVSS-BT scores; those are different metrics and are not substituted for the base scores.
