Starting from 2.53.6, 2.54.3, and 2.55.0, Zitadel only required multi factor authentication in case the login policy has either enabled requireMFA or requireMFAForLocalUsers. If a user has set up MFA without this requirement, Zitadel would consider single factor auhtenticated sessions as valid as well and not require multiple factors. Bypassing second authentication factors weakens multifactor authentication and enables attackers to bypass the more secure factor. An attacker can target the TOTP code alone, only six digits, bypassing password verification entirely and potentially compromising accounts with 2FA enabled. This vulnerability is fixed in 4.6.0, 3.4.3, and 2.71.18.
Zitadel is open-source identity infrastructure software. Prior to 4.6.0, 3.4.3, and 2.71.18, an attacker can perform an online brute-force attack on OTP, TOTP, and passwords. While Zitadel allows preventing online brute force attacks in scenarios like TOTP, Email OTP, or passwords using a lockout mechanism. The mechanism is not enabled by default and can cause a denial of service for the corresponding user if enabled. Additionally, the mitigation strategies were not fully implemented in the more recent resource-based APIs. This vulnerability is fixed in 4.6.0, 3.4.3, and 2.71.18.
ZITADEL is an open source identity management platform. Prior to 4.15.3, ZITADEL's external identity provider handler checks that the local user's email is verified but does not verify that the external IdP confirmed ownership of the same email before auto-linking by email, allowing a permissive provider account with a victim email address to be linked to the victim's local account. This issue is fixed in version 4.15.3.
ZITADEL is an open source identity management platform. Prior to 3.4.12 and 4.15.2, ZITADEL's OAuth2 and OIDC CodeExchange, RefreshToken, and device token flows fail to verify that the requesting client matches the client that initiated the authorization flow, allowing intercepted grants or refresh tokens to be exchanged under a different client. This issue is fixed in versions 3.4.12 and 4.15.2.
The open-source identity infrastructure software Zitadel allows administrators to disable the user self-registration. Due to a missing security check in versions prior to 2.64.0, 2.63.5, 2.62.7, 2.61.4, 2.60.4, 2.59.5, and 2.58.7, disabling the "User Registration allowed" option only hid the registration button on the login page. Users could bypass this restriction by directly accessing the registration URL (/ui/login/loginname) and register a user that way. Versions 2.64.0, 2.63.5, 2.62.7, 2.61.4, 2.60.4, 2.59.5, and 2.58.7 contain a patch. No known workarounds are available.
ZITADEL is an open source identity management platform. From version 4.0.0 to 4.12.0, a vulnerability in Zitadel's login V2 UI allowed users to bypass login behavior and security policies and self-register new accounts or sign in using password even if corresponding options were disabled in their organizaton. This issue has been patched in version 4.12.1.
