CVE-2026-107656

Summary

An authentication bypass flaw in FortiSandbox allows unauthenticated attackers to execute unauthorized code via crafted HTTP requests, enabling full system compromise including data theft, modification, and service disruption.

Exploitability

Highly exploitable due to network-accessible, no-privilege, no-user-interaction requirements; no public exploit is known but the CVSS score indicates trivial remote exploitation potential.

Blast radius

Successful exploitation grants full administrative control over affected FortiSandbox instances, risking compromise of sandboxed malware analysis data, lateral movement within the network, and disruption of security operations.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to FortiSandbox 5.0.7 or later for 5.0.x branches, 4.4.10 or later for 4.4.x branches, or 4.2.10 or later for 4.2.x branches; if no fixed version is available for your branch, immediately restrict HTTP access to the management interface and disable non-essential web services until patched.
