# phpMyFAQ: admins can grant themselves unrestricted rights across all languages

phpMyFAQ 4.2.0-alpha.2 before 4.2.0-beta drops per-right language restrictions when user rights are re-granted through UserController::updateUserRights. An administrator holding USER_EDIT can submit language-scoped rights to the update-rights API, including for their own account, and gain unrestricted FAQ create, edit and publish access in every language.

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

## How to check

- Check the installed phpMyFAQ version in the admin panel or `composer show phpmyfaq/phpmyfaq` and see whether it falls in 4.2.0-alpha.2 up to 4.2.0-beta
- Review which accounts hold USER_EDIT and whether any of them are language-restricted editors

## Fix

- Upgrade phpMyFAQ to `4.2.0-beta` or later
- Until upgraded, limit USER_EDIT to trusted administrators
