- 4.3MediumOct 30, 2026Bitwarden server Auth bypass / access controlCVE-2026-119414Bitwarden Server before 2026.10.1 on Entity Framework backends contains an authorization bypass vulnerability that allows organization members to add ciphers to collections they cannot edit. Attackers can call POST /api/ciphers/create, where a nulled UserId is treated as administrative, to inject vault items synced to read-only or inaccessible collections' members.
- 7.5HighSep 29, 2026bitwarden serverCVE-2026-101878Bitwarden Server 2025.6.0 before 2026.5.0 declares the @ExternalId parameter of the User_ReadBySsoUserOrganizationIdExternalId stored procedure as NVARCHAR(50) while the column it queries stores NVARCHAR(300), silently truncating the SSO login identifier on SQL Server deployments and allowing a user whose identity-provider identifier begins with another organization member's full 50-character identifier to authenticate as that member and obtain a victim-scoped access token.
- 8.7HighJul 8, 2026Bitwarden server Auth bypass / access controlCVE-2026-60104Bitwarden Server before 2026.6.0 does not verify that the email in a POST /auth-requests/admin-request body belongs to the authenticated caller, allowing a low-privileged organization member to obtain another user's vault key and a victim-scoped access token by creating a Trusted Device Encryption authentication request, bound to an attacker-controlled public key, that is readable from an unauthenticated endpoint once approved resulting in disclosure of the victim's vault key and account takeove
- 3.5LowJun 25, 2026Bitwarden server Code / command injectionCVE-2026-57522Bitwarden 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 arbitra
- 4.3MediumJun 25, 2026Bitwarden server Auth bypass / access controlCVE-2026-57521Bitwarden 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 org
- 7.1HighJun 25, 2026Bitwarden server Auth bypass / access controlCVE-2026-57520Bitwarden 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.
- 8.1HighMay 11, 2026Bitwarden serverCVE-2026-43640Bitwarden Server prior to v2026.4.1 does not require master-password re-authentication when retrieving or rotating an organization's SCIM API key, allowing an authenticated user with SCIM management privileges to obtain the key using only a valid session.
- 8.0HighMay 11, 2026Bitwarden server Auth bypass / access controlCVE-2026-43639Bitwarden Server prior to v2026.4.0 contains a missing authorization vulnerability that allows a provider service user to add an arbitrary organization to their provider via `POST /providers/{providerId}/clients/existing`, resulting in takeover of the target organization; self-hosted installations are unaffected as this endpoint is restricted to Cloud via SelfHosted(NotSelfHostedOnly = true).
- 5.4MediumMay 11, 2026Bitwarden server Auth bypass / access controlCVE-2026-43638Bitwarden Server prior to v2026.4.1 contains a missing authorization vulnerability that allows any authenticated user to write ciphers into an arbitrary organization via `POST /ciphers/import-organization` by submitting an empty `collections` array, which causes the server-side permission check to be skipped.
- 9.8CriticalMay 1, 2026Bitwarden cli Code / command injectionCVE-2026-42994Bitwarden CLI 2026.4.0 from 2026-04-22T21:57Z to 2026-04-22T23:30Z, when obtained from npm, had embedded malicious code. This is related to a Checkmarx supply chain incident.
