CVE-2026-86466 is a high-severity vulnerability in the Apache Airflow FAB provider affecting versions prior to 3.9.0. The issue arises because the Authentik OAuth path in the FAB auth manager does not validate the issuer or audience claims of the id_token it accepts. This allows an attacker with a valid token for another application from the same Authentik identity provider to authenticate as any user in Airflow without proper authorization. The vulnerability is fixed in version 3.9.0.
