{"schema_version": "1.6.1", "id": "CVE-2026-40948", "summary": "OAuth Login CSRF — Missing State Parameter in Keycloak Auth Manager", "details": "The Keycloak authentication manager in `apache-airflow-providers-keycloak` did not generate or validate the OAuth 2.0 `state` parameter on the login / login-callback flow, and did not use PKCE. An attacker with a Keycloak account in the same realm could deliver a crafted callback URL to a victim's browser and cause the victim to be logged into the attacker's Airflow session (login-CSRF / session fixation), where any credentials the victim subsequently stored in Airflow Connections would be harvestable by the attacker. Users are advised to upgrade `apache-airflow-providers-keycloak` to 0.7.0 or later.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "0.0.1"}, {"fixed": "0.7.0"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/airflow/pull/64114"}, {"type": "WEB", "url": "https://lists.apache.org/thread/kc0odpr70hbqhdb9ksnz42fkqz2xld9q"}]}
