Affected
- Oracle Outside In Technology (Image Export SDK), version 8.5.8
- Other versions or components: Unknown.
Fixed in
- Unknown. The fixed version must be confirmed in Oracle's October 2026 Critical Patch Update advisory.

Our recommendation
- Check software inventories and ask application vendors whether they embed Oracle Outside In libraries.
- If Outside In is used, apply the October 2026 Oracle Critical Patch Update once the fixed version is confirmed.
- Prioritise systems on which untrusted files are processed, such as multi-user servers or document-handling tools.
- Restrict local logon to these systems and monitor for suspicious file processing.
