NVD description
A flaw was found in the Client-Initiated Backchannel Authentication CIBA implementation within the keycloak-services component of Keycloak. This component handles advanced authentication flows where a client initiates a login on behalf of a user. The issue occurs because Keycloak fails to verify that a client is authorized to use the CIBA flow, allowing public clients to bypass security requirements. An attacker could use this flaw to trick a user into approving a login request, eventually gaining full access to the users account without needing a client secret.

Keycloak's CIBA login flow can be bypassed (CVE-2026-109082). Your identity provider is code too — it needs patch cycles like everything else you run. https://vulners.com/rapid7/RAPID7:CVE-2026-109082
