ZITADEL is an open source identity management platform. Prior to 4.15.3, ZITADEL Login V2 OIDC and SAML FailedPrecondition error paths return loginSettings.defaultRedirectUri to router.push without applying the isSafeRedirectUri check, allowing an organization or instance administrator to store a javascript or data URI that can execute in a user's browser when an affected login error path is reached. This issue is fixed in version 4.15.3.
