# Oracle JDeveloper: low-privilege local user reads a subset of data

Oracle JDeveloper 12.2.1.4.0 and 14.1.2.0.0 have a flaw that lets a low-privileged user who can log on to the machine where JDeveloper runs read a subset of its accessible data. The CVSS 3.1 score is 3.3 with confidentiality impact only, and the sources describe no integrity or availability loss.

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

## How to check

- Check the installed JDeveloper version in its About dialog or install directory; affected versions are `12.2.1.4.0` and `14.1.2.0.0`.

## Fix

- Move JDeveloper to a release newer than `12.2.1.4.0` or `14.1.2.0.0` as listed in Oracle's Critical Patch Update advisory (the sources do not name the fixed build).
