CVE-2026-86466: Apache Airflow FAB provider: FAB Authentik provider: id_token issuer/audience not validated

Apache Airflow FAB provider before 3.9.0 skips issuer/audience validation on Authentik id_tokens, allowing tokens minted for other clients to authenticate to Airflow.

CVE-2026-86466 affects apache-airflow-providers-fab before 3.9.0. The Authentik OAuth path in the FAB auth manager does not validate the issuer or audience claims of accepted id_tokens. An attacker holding a token minted by the same Authentik identity provider for a different client application can present it to Airflow and be authenticated. Severity is rated moderate by the reporter.
