Release Notes

keycloak/keycloak-js (keycloak-js)

v26.2.3

Compare Source

Highlights

This release of Keycloak JS addresses a regression that was introduced in version 26.2.2 affecting applications that use hash-based routing in combination with the fragment response mode.

Bug Fixes

URL hash fragments are now preserved correctly with 'fragment' response mode

A regression was introduced in version 26.2.2 that caused URL fragments with path-style routing (e.g., #/admin/maintenance/scripts) to be URL-encoded after the OAuth callback, breaking applications that use hash-based routing. This issue affected Angular, React, and other applications that rely on the hash portion of the URL for client-side routing.

v26.2.2

Highlights

This release of Keycloak JS focuses on addressing several regressions that were introduced by accident. We apologize for any inconvenience these issues may have caused and thank our community for reporting them quickly and helping to verify the fixes.

Bug Fixes

Destructuring public methods now works correctly

A regression was introduced that caused an error when destructuring public methods from a Keycloak instance. This pattern is commonly used in applications:

const { login, logout } = keycloak;
login(); // Previously failed with "Cannot read properties of undefined"

This issue has been resolved by binding all public methods to the class instance using arrow functions, ensuring that this is always correctly scoped regardless of how the method is called.

keycloak/keycloak-js#202

Hash fragments are now preserved in redirect URIs

A regression caused hash fragments in URLs to be stripped from redirect URIs, which broke navigation in applications that rely on fragment-based routing. For example, when logging in to the Keycloak Admin Console with a URL like http://localhost:8080/admin/master/console/#/demo/users/add-user, the user would be redirected to the default page instead of the intended fragment after authentication.

This also caused issues where redirect URIs would have a trailing slash added unexpectedly, breaking login flows for OIDC servers that perform strict URI matching.

The next major of Keycloak JS will start re-enforcing this constraint, as it is not allowed to pass fragments according to the specification.

keycloak/keycloak-js#151, keycloak/keycloak-js#205

Redirect URLs on different domains now work correctly

A regression prevented redirect URLs from being on a different domain than the application origin the navigation to fail with a security error. This affected users who use redirect services that forward authentication requests from an intermediate domain back to the application.

This behavior is likely to be changed in the future to only allow redirect URLs that are on the same origin as where Keycloak JS is initialized, in order to prevent possible open redirects. If this issue affects you please join the discussion.

v26.2.1

Compare Source

Highlights

This release of Keycloak JS is the first release after our initial announcement to split it off from the main project release cycle. This release is the result of a large internal refactor to make the code more maintainable and make use of modern JavaScript language features, as well as to introduce a new test suite with more comprehensive test coverage. Even though much has changed under the hood, this is a patch releases, and there should be no breaking changes for users, only bugfixes and small enhancements.
