# Oracle REST Data Services: GraphQL flaw leaks some accessible data

Oracle REST Data Services' GraphQL component has a flaw that lets an unauthenticated attacker over HTTP read a subset of data the service can access. The sources describe confidentiality impact only, with no code execution or data modification.

_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 (for example with `java -jar ords.war version` or the server's admin page) and see whether it falls in 24.2.0 through 26.1.0.
- Check whether the GraphQL endpoint is reachable from untrusted networks.

## Fix

- Move Oracle REST Data Services to a release newer than `26.1.0` once Oracle publishes a fixed build (the sources do not name the fixed version).
- Restrict network access to the GraphQL endpoint until patched.
