Title
Bitwarden Server < 2026.5.0 JSON Injection via Webhook Templates
Summary
Bitwarden Server before 2026.5.0 contains a JSON injection vulnerability in IntegrationTemplateProcessor.ReplaceTokens(), which substitutes user-controlled values into event-integration templates without JSON encoding. When an organization has configured an event integration whose template references a user-controlled token (such as #ActingUserName# or #UserName#, populated from a member's display name), an authenticated member can set their display name to JSON metacharacters and inject arbitrary key-value pairs into the rendered payloads delivered to webhook, SIEM, Slack, Teams, or Datadog endpoints, making injected fields indistinguishable from legitimate template output.

Title
Bitwarden Server < 2026.5.0 Broken Access Control via PreviewInvoiceController
Summary
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.

Title
Bitwarden Server < 2026.5.0 Privilege Escalation via Bulk User Remove Endpoint
Summary
Bitwarden Server before 2026.5.0 contains a privilege escalation vulnerability that allows authenticated Custom users with ManageUsers permission to remove Admin accounts from an organization by exploiting a missing role hierarchy check in the bulk user-remove endpoint. Attackers can supply Admin organization-user IDs in a bulk DELETE request to bypass the guard enforced on the single-user removal path, effectively removing one or more Admin accounts from an organization.

Title
Bitwarden Server < 2026.5.0 JSON Injection via Webhook Templates
Summary
Bitwarden Server before 2026.5.0 contains a JSON injection vulnerability in IntegrationTemplateProcessor.ReplaceTokens(), which substitutes user-controlled values into event-integration templates without JSON encoding. When an organization has configured an event integration whose template references a user-controlled token (such as #ActingUserName# or #UserName#, populated from a member's display name), an authenticated member can set their display name to JSON metacharacters and inject arbitrary key-value pairs into the rendered payloads delivered to webhook, SIEM, Slack, Teams, or Datadog endpoints, making injected fields indistinguishable from legitimate template output.

Title
Bitwarden Server < 2026.5.0 Broken Access Control via PreviewInvoiceController
Summary
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.

Title
Bitwarden Server < 2026.5.0 Privilege Escalation via Bulk User Remove Endpoint
Summary
Bitwarden Server before 2026.5.0 contains a privilege escalation vulnerability that allows authenticated Custom users with ManageUsers permission to remove Admin accounts from an organization by exploiting a missing role hierarchy check in the bulk user-remove endpoint. Attackers can supply Admin organization-user IDs in a bulk DELETE request to bypass the guard enforced on the single-user removal path, effectively removing one or more Admin accounts from an organization.
