CVE-2025-53895

ZITADEL has broken authN and authZ in session API and resulting session tokens

Published Jul 15, 2025 CVSS 4.0 · 7.7 High EPSS < 1% KEV · Not listed
Description
ZITADEL is an open source identity management system. Starting in version 2.53.0 and prior to versions 4.0.0-rc.2, 3.3.2, 2.71.13, and 2.70.14, vulnerability in ZITADEL's session management API allows any authenticated user to update a session if they know its ID, due to a missing permission check. This flaw enables session hijacking, allowing an attacker to impersonate another user and access sensitive resources. Versions prior to `2.53.0` are not affected, as they required the session token for updates. Versions 4.0.0-rc.2, 3.3.2, 2.71.13, and 2.70.14 fix the issue.
