Summary

IXP Manager is a full-stack web application for managing Internet Exchange Points. Prior to version 7.3.0, an authenticated user can view and edit a resource belonging to another user without authorization. The API-key edit/update path in `ApiKeyController` selects records by identifier without checking that `user_id` matches the caller, allowing access to another user's API-key record. This issue is fixed in version 7.3.0.
