Details

The Social User Export module enables users within Open Social to create an export of users and download this to a CSV file.

The module doesn't sufficiently check access when building the CSV file, allowing logged-in users without the manage members permission to be able to export all data from a selected user in certain scenarios.

This vulnerability is mitigated by the fact that an attacker must have the authenticated user role and the site must have the configuration set in such a way a logged in user is able to export users.
