# Oracle REST Data Services: low-privilege users can modify some data over HTTP

Oracle REST Data Services (ORDS) has a flaw in its ADP component that lets a low-privileged user with network access change or delete some data the service exposes. The sources describe an integrity impact only, with no confidentiality or availability loss.

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

## How to check

- Run `java -jar ords.war version` or check the ORDS version in the installation to see whether it falls in 24.2.0 through 26.1.0
- Check whether Automatic Data Persistence (ADP) features are in use on the ORDS instance
- unknown for other checks, the sources do not say

## Fix

- Move Oracle REST Data Services to a release after `26.1.0` once Oracle publishes the patched version
- unknown for specific patch version, the sources do not say
