What to do
- Check the affected products listed above against the official advisory's affected-versions table — that is where the exact ONTAP 9 release, ONTAP tool, or management product versions are named.
- If affected and a fixed release exists, plan the upgrade — see the ONTAP upgrade runbook.
- If exploitation is listed as "active", treat remediation as urgent and review exposure (management LIFs, ONTAP S3, SnapMirror endpoints).
- Harden in parallel: security hardening baseline and ransomware protection on ONTAP.
