# Oracle REST Data Services: low-privilege users can read some protected data

Oracle REST Data Services has a flaw in its ADP component that lets a low-privileged user reach data they should not see over HTTP. The sources describe only read access to a subset of accessible data, with no code execution or write impact.

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

## How to check

- Check the installed Oracle REST Data Services version against the affected range 24.2.0-26.1.0 (unknown how to read the version from the sources)
- unknown for other checks, since the sources do not say which configuration exposes the ADP component

## Fix

- Move Oracle REST Data Services to a release outside 24.2.0-26.1.0 as published in Oracle's Critical Patch Update (unknown exact fixed version in the sources)
