Palo Alto Networks has patched CVE-2026-0227, a high-severity (CVSS 7.7) vulnerability in GlobalProtect Gateway and Portal that allows unauthenticated denial-of-service by repeatedly forcing affected PAN-OS devices into maintenance mode; a proof-of-concept exploit exists and multiple PAN-OS and Prisma Access versions are listed as affected while Cloud NGFW is not impacted, so administrators should apply the vendor updates promptly to avoid service disruption.
