FortiSandbox Vulnerability Allows Attackers to Access Sensitive Information via Crafted HTTP Requests

Fortinet disclosed CVE-2026-26084 (CVSS 8.9), an unauthenticated information-disclosure flaw in the FortiSandbox web UI, urging upgrades.

Fortinet patched CVE-2026-26084, a CWE-284 improper access control flaw in the shared web UI of FortiSandbox, FortiSandbox Cloud, and FortiSandbox PaaS that lets unauthenticated attackers read sensitive data via crafted HTTP requests. Affected releases include FortiSandbox 5.0.0-5.0.5 and 4.4.0-4.4.8, Cloud 5.0.4-5.0.5, and PaaS 5.0.4-5.0.5; fixes arrive in 5.0.6+ and 4.4.9+, while FortiSandbox 5.2 and Cloud 4.4 are unaffected. The issue was found internally by Fortinet's Product Security team, and the company reports no evidence of exploitation in the wild. Disclosure carries only confidentiality impact, but exposed sandbox configurations and logs could aid follow-on attacks.
