# Oracle REST Data Services: high-privilege user can alter and read data

Oracle REST Data Services, in its Database Actions component, lets a user with high privileges and network access over HTTP modify, insert or delete some accessible data and read a subset of it. It can also cause a partial denial of service.

_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 (`java -jar ords.war version` or the ORDS install directory), since the affected range is 24.2.0 to 26.1.0
- Confirm whether Database Actions is enabled on the ORDS instance

## Fix

- Move Oracle REST Data Services to a release outside the affected range `24.2.0` to `26.1.0`, per Oracle's Critical Patch Update for this CVE
- unknown for the exact fixed version, as the sources do not say
