CVE-2026-0265 Details
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/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.

Bitsight, the leading provider in Cyber Risk Management, introduced the next-generation internet scanner Bitsight Groma in May 2024. This technology continuously scans the entire internet to discover assets, collect asset attribution evidence, and identify an ever-growing set of security observations, such as vulnerabilities and misconfigurations. Groma’s scanning activities presently encompass:


  • 40 million-plus monitored organizations
  • 250 million-plus host names
  • 4 billion-plus routable IPv4 and IPv6 addresses

Greynoise’s recent study testifies the speed of Bitsight Groma.
