CVE-2026-0281: PAN-OS: Information Disclosure Vulnerability in Management Web Interface (Severity: LOW)
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 https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .
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.
