2FAuth is a web app to manage Two-Factor Authentication (2FA) accounts and generate their security codes. Prior to 8.0.0, the recipients() method in app/Api/v1/Controllers/TwoFAccountShareController.php receives a caller-selected TwoFAccount through Laravel model binding but does not call the manageShares authorization policy before listing its recipients. When account sharing is enabled, an authenticated user can call GET /api/v1/twofaccounts/{victimId}/recipients for accounts owned by other users, enumerate registered user IDs and display names, test exact email addresses with filter[nameOrEmail], and inspect each account's sharing relationships. This issue is fixed in version 8.0.0.
