Attackers target critical FortiSandbox flaws as CISA issues patch order


Fortinet admins have two more reasons to clear their calendars after CISA confirmed a pair of critical FortiSandbox bugs are being actively exploited.

The two bugs, tracked as CVE-2026-39808 and CVE-2026-25089, both carry CVSS scores of 9.1 and affect FortiSandbox, FortiSandbox Cloud, and FortiSandbox PaaS.

Fortinet released fixes for CVE-2026-39808 in April and CVE-2026-25089 in June, warning in advisories published at the time that successful exploitation could lead to remote code execution via low-complexity attacks.
