Broken function-level authorization in Prospero Flow CRM before 5.5.3 lets any authenticated low-privileged user (e.g. the standard 'User'/'Usuario' role) read every bank account record belonging to their company via GET /api/bank-account. The API route is guarded only by auth:api with no permission gate — unlike the web equivalent, which enforces can('read bank') — so any valid bearer token returns sensitive banking data (IBAN, SWIFT/BIC, account identifiers). A vendor patch exists (5.5.3) and the fixing commit is public; there is no public exploit identified at time of analysis and the flaw is not in CISA KEV.

DescriptionCVE.org
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.
Executive ViewAI
Prospero Flow CRM before version 5.5.3 contains an authorization flaw allowing any employee with valid system credentials to access all company banking records and financial account details through an unprotected API endpoint. This exposes sensitive financial data to a broad internal audience and creates direct risk of fraud, account compromise, and regulatory non-compliance.
Within 24 hours, identify all Prospero Flow CRM deployments and confirm which are running versions before 5.5.3; obtain the 5.5.3 patch from the vendor immediately. Within 7 days, complete deployment of Prospero Flow CRM 5.5.3 across all instances, then validate that the /api/bank-account endpoint now enforces authorization controls consistent with the web interface. Within 30 days, audit Prospero Flow CRM API access logs from all dates when vulnerable versions were in use to identify any unauthorized /api/bank-account queries; escalate findings to legal and compliance for regulatory notification assessment.
Apply vendor patch.
