{"schemaVersion":3,"id":"CVE-2026-0310","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A buffer overflow vulnerability in the XML processing functionality of Palo Alto Networks PAN-OS® software enables an unauthenticated attacker with network access to the management web or dataplane interface to cause a denial of service (DoS) condition on VM-Series firewalls or execute arbitrary code with root privileges on the PA-Series firewalls.\n\nThe security risk posed by this issue is minimized when the management interface is restricted to only trusted internal IP addresses according to our recommended  best practice deployment guidelines
