CVE-2026-57521

Name of the Vulnerable Software and Affected Versions Bitwarden Server versions prior to 2026.5.0

Description Broken access control allows any authenticated user to access arbitrary organization billing data. By supplying an arbitrary organizationId to the PreviewInvoiceController endpoints, an attacker can bypass membership and authorization checks due to a missing ManageOrganizationBillingRequirement. This allows the retrieval of subscription status, Stripe-computed tax totals, and billing details derived from a target organization's customer and subscription data.

Recommendations Update Bitwarden Server to version 2026.5.0 or later.
