# Oracle REST Data Services: unauthenticated HTTP request can alter some stored data

Oracle REST Data Services versions 24.2.0 through 26.1.0 have a flaw in their Core component that an unauthenticated attacker can reach over HTTP. A successful attack lets the attacker update, insert or delete some of the data the service exposes.

## Fix

- Upgrade Oracle REST Data Services to a version after `26.1.0` as published in Oracle's Critical Patch Update advisory
- unknown for specific patched version number: the sources do not say
