  1. Validate SHA-256 checksum: ​​e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0​​
  2. Review PSIRT advisory FG-IR-24-412 for vulnerability details
  3. Execute CLI command exec backup config flash before installation

Organizations requiring temporary access must verify service contracts through Fortinet’s support portal, with typical authorization processing within 4 business hours.

Note: Always test firmware upgrades in isolated environments. Refer to FortiOS 7.2 Release Notes for full technical documentation.
