CVE-2026-0281 PAN-OS: Information Disclosure Vulnerability in Management Web Interface
Description
An information disclosure vulnerability in Palo Alto Networks PAN-OS® software enables an unauthenticated attacker with network access to the management web interface to obtain web session tokens. This requires a legitimate user to first click on a malicious link provided by the attacker.
The security risk posed by this issue is minimized by restricting access to the management web interface to only trusted internal IP addresses according to our recommended best practice deployment guidelines.
This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series).
Cloud NGFW and Prisma® Access are not impacted by this vulnerability.
Product Status
| Versions | Affected | Unaffected |
|---|---|---|
| Cloud NGFW | None | All |
| PAN-OS 12.1 | < 12.1.8 | >= 12.1.8 |
| PAN-OS 11.2 | < 11.2.13 | >= 11.2.13 |
| PAN-OS 11.1 | < 11.1.16 | >= 11.1.16 |
| PAN-OS 10.2 | All | None |
| Prisma Access | None | All |
Required Configuration for Exposure
No special configuration is required to be affected by this issue.
Severity: LOW, Suggested Urgency: MODERATE
The risk is highest when you allow access to the management interface from external IP addresses on the internet.
LOW
- CVSS-BT: 2.1 /CVSS-B: 5.9 (CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/AU:N/R:A/V:D/RE:M/U:Amber)
You can reduce the risk of exploitation by restricting access to a jump box that is the only system allowed to access the management interface.
LOW
- CVSS-BT: 1.7 /CVSS-B: 5.6 (CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/AU:N/R:A/V:D/RE:M/U:Amber)
Exploitation Status
Palo Alto Networks is not aware of any malicious exploitation of this issue.

Workarounds and Mitigations
The vast majority of firewalls already follow Palo Alto Networks' and industry best practices. However, if you have not already, we strongly recommend that you secure access to your management interface according to our best practice deployment guidelines. Specifically, you should restrict management interface access to only trusted internal IP addresses.
