JSON

A flaw was found in Keycloak’s OIDC component in the “checkLoginIframe,” which allows unvalidated cross-origin messages. This flaw allows attackers to coordinate and send millions of requests in seconds using simple code, significantly impacting the application’s availability without proper origin validation for incoming messages.

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
