Vaultwarden through 1.37.3 omits organization membership status validation from three cipher access-restriction queries, allowing revoked and not-yet-confirmed members to retain read, write, delete, and attachment access to organization ciphers. Attackers with revoked or pending membership can exploit missing status filters in get_user_collections_access_flags, get_group_collections_access_flags, and is_in_full_access_group to access protected cipher data server-side.
