No fixed version is named in the NVD record, so remediation follows the IBM bulletin rather than a version guess here.

What to do

  1. Inventory every Planning Analytics deployment, including test, training, and individually managed instances.
  2. Apply the vendor fix or upgrade exactly as directed in the linked vendor bulletin or advisory.
  3. Restrict network access to Planning Analytics while remediation is underway, especially for internet-facing instances.
  4. Review application and server logs for administrator logins from new locations, new admin accounts, and changes to models or security settings by unfamiliar users.
  5. Check for accounts, content, or configuration created outside normal change processes, and rotate exposed credentials where access cannot be ruled out.
  6. Verify the deployed version or patch level after remediation.

Management note

Planning Analytics holds budgets and forecasts people act on. Unauthorized admin there is both a security and a data-integrity problem. Patch and audit admin accounts.
