Prior to 1.35.5, Vaultwarden allows an unconfirmed organization owner to purge the entire organization vault. The organization invite flow uses a two-step process: accepting an invite transitions membership from Invited to Accepted, and a separate confirmation by an existing owner upgrades it to Confirmed. The POST \/api\/ciphers\/purge endpoint uses plain Headers and only checks that the membership type is Owner without verifying that the membership status is Confirmed. An authenticated user who has been invited as an organization owner and has accepted the invite and has not yet been confirmed can call this endpoint to hard-delete all ciphers and attachments in the organization,<br \/>\ncausing immediate organization-wide data loss. This vulnerability is fixed in 1.35.5.<\/p>\n<p>  Severity: 8.1 | HIGH<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-43913 Published : May 11, 2026, 11:20 p.m. | 2\u00a0hours, 37\u00a0minutes ago Description :Vaultwarden is a Bitwarden-compatible server written in Rust.
