Description

Impact

RefreshTokens is an OAuth 2.0 feature that allows applications to retrieve new access tokens and refresh the user's session without the need for interacting with a UI.

RefreshTokens were not invalidated when a user was locked or deactivated. The deactivated or locked user was able to obtain a valid access token only through a refresh token grant.

When the locked or deactivated user’s session was already terminated (“logged out”) then it was not possible to create a new session. Renewal of access token through a refresh token grant is limited to the configured amount of time (RefreshTokenExpiration).

Patches

2.x versions are fixed on >= 2.17.3
2.16.x versions are fixed on >= 2.16.4

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

Workarounds

Ensure the RefreshTokenExpiration in the OIDC settings of your instance is set according to your security requirements.
