CVE-2026-0317: PAN-OS: Denial of Service Vulnerability
CVE-2026-0317
Summary
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).
