Other vulnerabilities in Prospero Flow CRM
See all- CVE-2026-77780Medium
Roskus Prospero Flow CRM versions 4.9.1 through 5.14.0 have an authorization bypass vulnerability via user-controlled key in the transaction save endpoint. A user with transaction creation permissions can disclose another company's bank account name, bank name, and card last four digits by providing a foreign `bank_account_id` or `bank_card_id` in POST /transaction/save.
- CVE-2026-77759High
Roskus Prospero Flow CRM versions 5.0.0 through 5.3.5 have an authorization bypass through user-controlled key in the transaction API. An authenticated user can read transactions of other companies on the same instance via an incremented identifier in GET /api/transaction/{id}, without company scoping or permission check.
- CVE-2026-59237Medium
The vulnerability allows an authenticated user to bypass authorization by manipulating numeric IDs in REST API endpoints. The Order and OrderItem controllers in Prospero Flow CRM before version 5.5.3 do not verify record ownership by the user's company, enabling reading, modifying, and deleting orders and order items belonging to other tenants.
- CVE-2026-59236Medium
A vulnerability in Prospero Flow CRM before version 5.14.0 allows an authenticated user to bypass authorization via a user-controlled key (CWE-639) in the Excel import functionality. An attacker can create customer, lead, and product records in another company's tenant by uploading a spreadsheet with a manipulated company_id column.
- CVE-2026-59234Medium
A vulnerability in Prospero Flow CRM before version 5.5.3 allows an authenticated attacker to delete arbitrary calendar events of other users by manipulating the {id} parameter in a GET request to /calendar/event/delete/{id}. The lack of ownership check (user_id/company_id) before deletion leads to unauthorized data destruction.
Original NVD description (English source)
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.
