|---|---|---|---|---|---|---|
| CVE-2026-43640 | Bitwarden 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. | [email protected] | 8.6 | 0.06% | 2026-05-11 | 2026-05-16 |
| CVE-2026-43639 | Bitwarden 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). | [email protected] | 8.9 | 0.04% | 2026-05-11 | 2026-05-16 |
| CVE-2026-43638 | Bitwarden 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. | [email protected] | 5.3 | 0.03% | 2026-05-11 | 2026-05-16 |

| CVE-2018-25081 | Bitwarden through 2023.2.1 offers password auto-fill within a cross-domain IFRAME element.
