Detailsinfo

A vulnerability was found in Zitadel up to 2.70.9/2.71.8. It has been declared as problematic. This vulnerability affects an unknown code of the component API. The manipulation with an unknown input leads to a session expiration vulnerability. The CWE definition for the vulnerability is CWE-613. According to WASC, "Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization." As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2025-46815 since 04/30/2025. The exploitation appears to be difficult. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available.

Upgrading to version 2.70.10, 2.71.9 or 3.0.0 eliminates this vulnerability. The upgrade is hosted for download at github.com. Applying the patch b1e60e7398d677f08b06fd7715227f70b7ca1162 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
