Critical vulnerabilities in Fortinet CVE-2025-59718, CVE-2025-59719 exploited in the wild


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.

Current information indicates that the two CVEs have the same root cause and are differentiated by the products affected: CVE-2025-59719 specifically affects FortiWeb, while CVE-2025-59718 affects FortiOS, FortiProxy, and FortiSwitchManager. While the vulnerable FortiCloud SSO feature is disabled by default in factory settings, it is automatically enabled when a device is registered to FortiCare via the GUI, unless an administrator explicitly opts out.
