CVE-2024-39683

ZITADEL is an open-source identity infrastructure tool. ZITADEL provides users the ability to list all user sessions of the current user agent (browser). Starting in version 2.53.0 and prior to versions 2.53.8, 2.54.5, and 2.55.1, due to a missing check, user sessions without that information (e.g. when created though the session service) were incorrectly listed exposing potentially other user's sessions. Versions 2.55.1, 2.54.5, and 2.53.8 contain a fix for the issue. There is no workaround since a patch is already available.

Impact

ZITADEL provides users the ability to list all user sessions of the current user agent (browser) by API and in the Console UI.

Due to a missing check, user sessions without that information (e.g. when created though the session service) were incorrectly listed exposing potentially other user's sessions.

Note that the Login UI was never affected and there was no possibility to take over such a session.

Patches

2.x versions are fixed on >= 2.55.1 2.54.x versions are fixed on >= 2.54.5 2.53.x versions are fixed on >= 2.53.8

ZITADEL recommends upgrading to the latest versions available in due course.

Workarounds

There is no workaround since a patch is already available.
