# Oracle REST Data Services: ADP flaw lets low-privileged users change data

Oracle REST Data Services versions 24.2.0 through 26.1.0 have a flaw in the ADP component. A low-privileged attacker with network access over HTTP can read a subset of accessible data and insert, update or delete some of it.

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

## How to check

- Check the installed ORDS version with `java -jar ords.war version` or the ORDS admin page, and compare it to the affected range 24.2.0-26.1.0
- Confirm whether the ADP component is in use on the instance (unknown from sources)

## Fix

- Move Oracle REST Data Services to a release newer than `26.1.0` (the patched version is unknown from sources; check Oracle's July 2026 Critical Patch Update advisory)
