- Inventory: find every instance of the affected product and version (include internet-facing and forgotten ones).
- Patch or mitigate per the vendor advisory; if you cannot patch, remove internet exposure or apply the vendor workaround.

- Rotate credentials and secrets stored on or used by the affected system if compromise cannot be ruled out.
