Name of the Vulnerable Software and Affected Versions Vaultwarden versions prior to 1.36.0

Description The SSO discovery and pre-validation flow returns organization-related SSO metadata, including organizationIdentifier values, for arbitrary email addresses. This allows a valid pre-validation JWT (JSON Web Token, a compact, URL-safe means of representing claims to be transferred between two parties) to be obtained using only the discovered identifier, which enables the enumeration of SSO-enabled organizations and abuse of the authentication workflow.

Recommendations Update to version 1.36.0.
