CVE-2025-46815
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.

dbcve · scoped2.70.102.71.9
Upgrade to ZITADEL 2.70.10 (for 2.70.x), 2.71.9 (for 2.71.x), or 3.0.1+ (for 3.0.0)
- 1. Back up your current ZITADEL database and configuration files before starting the upgrade process.
- 2. Stop the currently running ZITADEL instance to prevent data inconsistency during upgrade.
- 3. Retrieve the appropriate version of ZITADEL based on your current version: for ZITADEL 2.70.x upgrade to 2.70.10; for ZITADEL 2.71.x upgrade to 2.71.9; for ZITADEL 3.0.0 upgrade to 3.0.1 or later.
- 4. Replace the existing ZITADEL binary or container image with the new version.
- 5. Review and update any configuration changes required by the new version using the ZITADEL migration guides.
- 6. Start the upgraded ZITADEL instance and verify all services initialize correctly.
- 7. Test the Session API and IdP intent flow to confirm the vulnerability is resolved.
- 8. Verify that existing user sessions and MFA configurations work as expected after the upgrade.
