Description

Vaultwarden is an unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs. Vaultwarden versions 1.34.3 and prior are susceptible to a 2FA bypass when performing protected actions. An attacker who gains authenticated access to a user’s account can exploit this bypass to perform protected actions such as accessing the user’s API key or deleting the user’s vault and organisations the user is an admin/owner of . This issue has been patched in version 1.35.0.
