CVE-2025-46215Network attack vector

Unauthenticated scan evasion via crafted file

Published Nov 18, 2025 · Updated Nov 18, 2025

Improper isolation in Fortinet FortiSandbox allows remote attackers to evade sandbox scans by submitting a crafted file. Fortinet has not disclosed the affected component or the operation that mishandles the file; the public record states only that crafted input bypasses sandbox analysis. No authentication or user interaction is required, but the file must reach the scan workflow; the reported consequence is loss of scan-result integrity.
