# Profile Builder WordPress plugin: contributors can gain higher privileges

Profile Builder, a WordPress plugin, has a flaw that lets a Contributor-level account escalate its privileges. The sources do not say what the attacker gains beyond that role change.

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

## How to check

- Check the installed Profile Builder plugin version in the WordPress admin under Plugins; affected versions are `4.0.5` and below.
- Review user accounts with the Contributor role for any that have been promoted unexpectedly.

## Fix

- Move Profile Builder to a version later than `4.0.5`; the sources do not name the exact fixed version.

## Timeline

## From the sources
