Our recommendation
- Check whether Oracle Cost Management is licensed and used.
- Apply the October 2026 Oracle CPU fix for E-Business Suite once the patch number is confirmed, together with the Database and Fusion Middleware patches it depends on.
- Until patched, restrict HTTP access to E-Business Suite and review accounts that allow self-registration or weak account control.
- Monitor E-Business Suite web and application logs for unusual access.
