A recently disclosed pair of vulnerabilities affecting Fortinet devices—CVE-2025-59718 and CVE-2025-59719—are drawing urgent attention after confirmation of their active exploitation in the wild. The vulnerabilities carry a critical CVSSv3 score and allow an unauthenticated remote attacker to bypass authentication using a crafted SAML message, ultimately gaining administrative access to the device.
