CVE-2024-39683: ZITADEL Vulnerable to Session Information Leakage

Published Jul 3, 2024
·
Updated

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.
