CVE-2026-16089 (opens in a new tab)How to fix?
There is no fixed version for org.keycloak:keycloak-services.
Overview
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 Authorization Bypass Through User-Controlled Key due to the OAuth 2.0 authorization code handling. An attacker can obtain access tokens for a victim’s identity by intercepting an authorization code and redeeming it with their own client. The affected code path does not bind the authorization code to the client that originally requested it, so a stolen code can be substituted during token exchange and used to log in as the victim.
