Vaultwarden is an unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs. Prior to version 1.35.4, an authenticated regular user can specify another user’s cipher_id and call "PUT /api/ciphers/{id}/partial" Even though the standard retrieval API correctly denies access to that cipher, the partial update endpoint returns 200 OK and exposes cipherDetails (including name, notes, data, secureNote, etc.). This issue has been patched in version 1.35.4.

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.
