org.keycloak:keycloak-services@16.1.0 vulnerabilities

org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

Affected versions of this package are vulnerable to URL Redirection to Untrusted Site ('Open Redirect') due to a misconfiguration flaw in the validation of redirect URIs. An attacker can redirect users to an arbitrary URL and potentially expose sensitive information such as authorization codes, leading to session hijacking.

Note: This is only exploitable if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1.

Upgrade org.keycloak:keycloak-services to version 22.0.13, 24.0.8, 25.0.6 or higher.

org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

Upgrade org.keycloak:keycloak-services to version 24.0.5 or higher.

org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

Affected versions of this package are vulnerable to Insecure Storage of Sensitive Information through PAR (Pushed authorization request) clients when using client_secret_post based authentication. This vulnerability derived from client-provided parameters that were included in plain text within the KC_RESTART cookie, which the authorization server returned in its HTTP response to a request_uri authorization request.

To exploit this vulnerability, an attacker needs to intercept the HTTP response from the authorization server, which might result in the disclosure of sensitive information.

Note

If you use OIDC confidential clients together with PAR and use client authentication based on client_id and client_secret sent as parameters in the HTTP request body (method client_secret_post specified in the OIDC specification), it is highly encouraged to rotate your clients' client secrets after upgrading to this version.
