Workaround
- Restrict access to the ODI console to management networks or VPN only and block it from the internet until patched.

Our recommendation
- Identify all ODI installations and check whether their console is reachable from the internet, partner networks or broad internal segments.
- Apply the Oracle October 2026 Critical Patch Update to all affected ODI versions as a priority, and verify the fix in the Oracle advisory.
- Until patched, restrict console access as described above.
