# Dromara domain-admin: authenticated users can read other groups' member lists

Dromara domain-admin versions before 1.6.79 let any logged-in user call the POST /api/getGroupUserList endpoint for groups they do not belong to. An attacker can walk through sequential group IDs to collect member usernames, leader and edit flags, and group owner usernames.

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

## How to check

- Check the installed domain-admin version is below `1.6.79`
- Review whether the `/api/getGroupUserList` handler checks group membership before returning data

## Fix

- Upgrade domain-admin to `1.6.79` or later

## From the sources

Dromara domain-admin before 1.6.79 contains a missing authorization vulnerability in the POST /api/getGroupUserList handler that allows authenticated users to read other groups' members. Attackers can enumerate sequential group_id values to disclose member usernames, leader and edit-permission flags, and owner usernames of groups they do not belong to.
