Description OSIDB Bzimport 2026-03-04 22:01:27 UTC 
Vaultwarden is an unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs. Prior to version 1.35.4, when a Manager has manage=false for a given collection, they can still perform several management operations as long as they have access to the collection. This issue has been patched in version 1.35.4.
