Description
Lago through 1.55.0 contains an authorization bypass vulnerability in Invoices::Payments::StripeService that allows users of one organization to mark another organization's invoice as paid due to an unscoped invoice lookup. Attackers controlling their organization's Stripe integration can sign a payment_intent.succeeded event carrying a victim invoice UUID to unlock wallet top-ups or payment-gated subscriptions.
