CVE-2026-26083 CRITICAL NEWS Act Now

Remote code execution in Fortinet FortiSandbox 4.4.x through 5.0.x (on-premises, Cloud, and PaaS deployments) allows unauthenticated attackers to execute arbitrary code or commands via crafted HTTP requests. This CWE-862 missing authorization flaw affects sandbox analysis appliances across multiple deployment models with CVSS 9.8 (critical) severity. Fortinet has published vendor advisory FG-IR-26-136. No CISA KEV listing or public POC identified at time of analysis, though the trivial attack complexity (AC:L) and network vector without authentication (PR:N) indicate high exploitability if technical details emerge.

CVE-2026-39813 CRITICAL POC NEWS Act Now

Path traversal in Fortinet FortiSandbox 4.4.0-4.4.8 and 5.0.0-5.0.5 enables remote unauthenticated attackers to achieve full system compromise. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N), the vulnerability permits network-based exploitation without credentials or user interaction, leading to complete confidentiality, integrity, and availability impact. Despite critical severity, EPSS score of 0.06% (18th percentile) indicates low observed exploitation probability. No active exploitation confirmed (not in CISA KEV). SSVC framework marks it as automatable with total technical impact but no current exploitation. The incomplete CVE description (placeholder text for attack vector) suggests early disclosure; verify completeness with Fortinet advisory FG-IR-26-112.

CVE-2025-53679 HIGH This Week

Authenticated OS command injection in Fortinet FortiSandbox (versions 5.0.0-5.0.2, 4.4.0-4.4.7, all 4.2.x, all 4.0.x) and FortiSandbox Cloud (24.1 and all 23.x) allows a high-privileged remote attacker to execute arbitrary commands by sending crafted HTTP/HTTPS requests to the management interface. No public exploit identified at time of analysis and the issue is not currently listed in CISA KEV, but the breadth of affected major versions and the network-reachable attack surface make this a notable post-authentication risk for security appliance operators.
