Description

Cross-Site Request Forgery (CSRF) in the OrderConfirmController at GET /order/confirm/{order_number} in Roskus Prospero Flow CRM before 5.15.11 allows an unauthenticated attacker to confirm any order on behalf of an authenticated user by directing them to a crafted page. Laravel's VerifyCsrfToken middleware enforces CSRF tokens only on POST, PUT, PATCH, and DELETE requests; the Route::get declaration leaves this state-changing action unprotected. Session cookies configured with SameSite=Lax are automatically included in top-level cross-site navigation, so a single link click triggers OrderConfirmController::confirm() and transitions the target order from pending to confirmed without user authorization. Because order numbers are sequential integers, an attacker can enumerate and confirm all existing orders in a single automated sweep.
