A public proof-of-concept exploit for a critical FortiSandbox vulnerability (CVE-2026-39808) enables unauthenticated root remote command execution by injecting commands into the jid parameter of the /fortisandbox/job-detail/tracer-behavior endpoint; FortiSandbox 4.4.0–4.4.8 are confirmed vulnerable, a vendor patch exists outside that range, and organizations are advised to patch immediately, restrict access, and monitor for exploitation attempts.
