Technical details
The vulnerability is an authentication bypass in the stripeCustomerPortal GraphQL mutation that fails to validate user credentials or authorization before processing requests. The mutation creates a customer portal session linked to any tenant's Stripe account without checking if the requester is authenticated or has permission to access that tenant's data. An attacker with network access to the GraphQL endpoint can exploit this remotely by calling the mutation with an arbitrary tenant identifier. This allows unauthorized access to billing and subscription data for all affected organizations, affecting confidentiality and potentially integrity of financial records.
