Description
An issue in usememos v0.27.1 allows a remote attacker to achieve account takeover via the ssoCredentials branch of the SignIn handler in server/router/api/v1/auth_service.go, because SSO identity is matched only on an attacker-controllable identifier without binding to the IdP's stable subject claim.
