CVE-2026-57521 Details
Description
Bitwarden Server before 2026.5.0 contains a broken access control vulnerability that allows any authenticated user to access arbitrary organization billing data by supplying an arbitrary organizationId to the PreviewInvoiceController endpoints without membership or authorization checks. Attackers can exploit the missing ManageOrganizationBillingRequirement on the preview invoice endpoints to retrieve Stripe-computed tax totals, subscription status, and billing details derived from any target organization's real customer and subscription data.
A broken access control vulnerability has been identified in Bitwarden Server versions prior to 2026.5.0. This vulnerability allows any authenticated user to access arbitrary organization billing data by supplying an arbitrary organization ID to the PreviewInvoiceController endpoints. The issue arises because these endpoints lack proper membership and authorization checks, enabling unauthorized access to sensitive billing information.
Users can update to Bitwarden Server version 2026.5.0 or later, where this vulnerability has been fixed.
