UserSearchAPIhas noauthentication_classes = [CustomizePermission]declaration, making it accessible without any JWT. The removed filter was the only guard preventing private profiles from appearing in results.user_settings.is_publicdefaults to0(false) in the schema, so the majority of users who never explicitly opted in are now discoverable — including theirid,full_name,muid,profile_pic,karma,organizations, andinterest_groups— by any unauthenticated caller.Every other privacy boundary in the codebase enforces this invariant:
profile_view.pygates five separate profile sub-endpoints onis_public,mulearner_views.pyfilters withuser_settings_user__is_public=True, andexternal_api_views.pyrejects private profiles with 403. Removing this single line breaks the contract users relied on when they left (or set) their visibility to private.
