The critical flaw, found is CVE-2026-26083 (FG-IR-26-136), which is a missing permission issue that impacts FortiSandbox, FortiSandbox Cloud, and FortiSandbox PaaS.
This serious security issue can be accessed through a GUI and does not need any login. This means a remote attacker could reach private functions or sensitive sandbox analysis data without any credentials.
Affected versions include FortiSandbox 5.0 and 4.4, FortiSandbox Cloud 24, 23, and 5.0, and FortiSandbox PaaS versions spanning 22.1 through 23.4. The unauthenticated attack surface makes this the highest-priority patch in the batch.
| CVE | Product | Severity | Vector | Auth Required |
|---|---|---|---|---|
| CVE-2026-26083 | FortiSandbox / Cloud / PaaS | Critical | GUI | No |
| CVE-2025-53680 | FortiAP, FortiAP-U, FortiAP-W2 | Medium | CLI | Yes |
| CVE-2025-53870 | FortiAP, FortiAP-W2 | Medium | CLI | Yes |
| CVE-2025-67604 | FortiAnalyzer, FortiManager | Medium | API | Yes |
| CVE-2025-53844 | FortiOS | Medium | CAPWAP | Yes |
Organizations using affected Fortinet products should fix CVE-2026-26083 right away because it is Critical and can be attacked without any login.
For medium-severity flaws, security teams should use available patches in their next maintenance time, limit CLI and API access to trusted admins only, and watch internal network traffic for unusual CAPWAP or API activity.
Fortinet’s PSIRT advisory page is the best place to find details about patch versions and workarounds.
