Description

Vaultwarden is a Bitwarden-compatible server written in Rust. Prior to 1.36.0, Vaultwarden's SSO discovery and pre-validation flow returned organization-related SSO metadata including organizationIdentifier values for arbitrary email addresses and allowed a valid pre-validation JWT to be obtained with only the discovered identifier, enabling SSO-enabled organization enumeration and authentication workflow abuse. This issue is fixed in version 1.36.0.
