CVE-2026-21643: FortiClient EMS SQL injection

Use AI to implement and verify

1. Inspect: Inventory every owned instance of Fortinet / FortiClientEMS; record its location, owner, exact version, exposure, and the read-only evidence used to decide whether it is affected.
2. Change: Propose the smallest change that implements the stable reviewed recipe: Inventory every standalone or HA EMS server, deployment artifact, database, and reinstall/recovery path. Exclude FortiEMS Cloud and endpoint agents from the server-upgrade matrix, but preserve endpoint compatibility evidence. Show the exact diff or command plan and dependency impact; do not apply it yet.
3. Approval: Require the repository, service, or security owner to approve the affected asset, target version, maintenance window, backup, and mutation scope before any write.
4. Test: After approval, inspect generated queries to confirm values remain bound parameters and cannot alter identifiers, operators, or clauses and save the commands and results.
5. Rollback: Define failure triggers before the change. If a trigger fires, stop the rollout and use the approved vendor recovery, configuration-backup, or HA failover procedure; restore only firmware or an image that the cited vendor evidence confirms is not affected. Never automatically downgrade into an affected version; if no known-safe recovery target exists, isolate the asset and escalate to its owner and vendor. Preserve the failure evidence for triage.

Stop before mutation if product identity, affected range, fixed version, ownership, or approval is unresolved.
Return an inventory, source decision, proposed diff/commands, approval request, test evidence, rollback status, and unresolved assumptions.
