ZITADEL Allows IdP Intent Token Reuse

The identity infrastructure software ZITADEL offers developers the ability to manage user sessions using the Session API. This API enables the use of IdPs for authentication, known as idp intents. Following a successful idp intent, the client receives an id and token on a predefined URI. These id and token can then be used to authenticate the user or their session. However, prior to versions 3.0.0, 2.71.9, and 2.70.10, it was possible to exploit this feature by repeatedly using intents. This allowed an attacker with access to the application’s URI to retrieve the id and token, enabling them to authenticate on behalf of the user. It's important to note that the use of additional factors (MFA) prevents a complete authentication process and, consequently, access to the ZITADEL API. Versions 3.0.0, 2.71.9, and 2.70.10 contain a fix for the issue. No known workarounds other than upgrading are available.

ZITADEL 安全漏洞

ZITADEL是瑞士ZITADEL开源的一个 Auth0、Firebase Auth、AWS Cognito 以及为容器和无服务器时代构建的 Keycloak 的现代开源替代方案。 ZITADEL 3.0.0之前版本、2.71.9之前版本和2.70.10之前版本存在安全漏洞，该漏洞源于Session API中可重复使用intents，可能导致身份验证绕过。
