Description

Missing Authorization (CWE-862) in BankAccountListController (app/Http/Controllers/Api/BankAccount/BankAccountListController.php), exposed at GET /api/bank-account, in Prospero Flow CRM <5.5.3, which allows a remote, authenticated attacker holding a low-privileged role (e.g. the "User"/"Usuario" role) to read arbitrary bank account records belonging to their company by sending an authenticated request to the endpoint with a valid bearer token, because the API route is protected only by the auth:api middleware and carries no permission gate, unlike the equivalent web route, which enforces can('read bank'), and the handler resolves records with Account::where('company_id', Auth::user()->company_id)->get(), performing only company scoping and no role or permission check before returning the data. This results in the unauthorized disclosure of sensitive banking information (e.g. IBAN, SWIFT/BIC, account identifiers) to users who should not have access to it.
