What is CVE-2026-43913?

Vaultwarden, a Bitwarden-compatible password manager server, contains a significant security flaw that allows unauthorized organization owners to purge the entire organization vault. This vulnerability arises from the absence of adequate verification processes in the organization invite flow. An invited owner, upon acceptance of their invite but before achieving 'Confirmed' status, can exploit the POST /api/ciphers/purge endpoint to permanently delete all ciphers and attachments, jeopardizing sensitive data and leading to instant organization-wide data loss. The issue has been rectified in version 1.35.5.
