Both vulnerabilities were patched by Fortinet in April 2026.\\n\\nCVE-2026-25089 (CVSS score: 9.1), on the other hand, was fixed last week, with Fortinet describing it as an operating system command injection impacting FortiSandbox, FortiSandbox Cloud, and FortiSandbox PaaS WEB UI that could allow an unauthenticated attacker to execute unauthorized commands via specifically crafted HTTP requests.\\n\\nDefused Cyber noted that the exploit for CVE-2026-25089 not only shows signs of being developed using an artificial intelligence (AI) model, but is also faulty. A working exploit for the vulnerability has not been publicly disclosed.\\n\\nVulnerabilities in Fortinet appliances have become a lightning rod for attackers in recent years. In April 2026, Fortinet released out-of-band patches for a critical security flaw impacting FortiClient EMS (CVE-2026-35616, CVSS score: 9.1) that it said has been exploited in the wild.\\n\\nFound this article interesting?
