# phpMyFAQ: admins can delete higher-privileged groups via crafted request

phpMyFAQ 4.2.0-alpha before 4.2.0-beta lets an authenticated administrator with the GROUP_DELETE right delete groups above their privilege level by sending a crafted groupId to the group delete endpoint. Deleting those groups permanently removes them and strips inherited rights from their members.

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

## How to check

- Check the installed version of phpMyFAQ in the application's version file or admin footer, and see whether it is between `4.2.0-alpha` and `4.2.0-beta`.
- Review which administrator accounts hold the GROUP_DELETE right.

## Fix

- Upgrade phpMyFAQ to `4.2.0-beta` or later.

## From the sources

phpMyFAQ from 4.2.0-alpha before 4.2.0-beta contains a missing authorization vulnerability in GroupController::deleteGroup() that omits privilege-level checks on target groups. Authenticated non-SuperAdmin administrators holding GROUP_DELETE can send a crafted groupId to /admin/api/group/delete to permanently destroy higher-privileged groups and strip members' inherited rights.
