# Oracle E-Business Suite: iSupplier Portal flaw exposes data to low-privileged users

Oracle E-Business Suite's iSupplier Portal, in the Internal Operations component, has a flaw that lets an attacker with low privileges and network access over HTTP reach data they should not see. Successful exploitation can expose critical data or all data the iSupplier Portal can access, with no effect on integrity or availability.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Confirm the Oracle E-Business Suite release in use; the affected supported versions are `12.2.3` through `12.2.15`
- Check whether the iSupplier Portal is deployed and reachable over HTTP
- Review the July 2026 or later Oracle Critical Patch Update advisory for the patch level in use (unknown from the sources)

## Fix

- Apply the Oracle Critical Patch Update fix for Oracle E-Business Suite iSupplier Portal (the fixed version is unknown from the sources)
- Move to a supported E-Business Suite release outside the affected range `12.2.3` to `12.2.15` if a patch is not available
