BIT-AIRFLOW-2026-68971 Apache Airflow: Cross-team authorization bypass in the asset materialization and dag-run result endpoints

Apache Airflow's asset materialization endpoint POST /api/v2/assets/assetid/materialize and the XCom result check on waitdagrununtilfinished authorized the target Dag without its team, unlike every other authorization site. A team-aware auth manager distinguishes a team-scoped Dag from a global o...

BIT-AIRFLOW-2026-59242 Apache Airflow: Arbitrary airflow.* class instantiation on the API server via the XCom deserialize endpoint

Apache Airflow's XCom GET /api/v2/.../xcomEntries/key?deserialize=true endpoint passed a string-literal payload through BaseXCom.deserializevalue without the checkforbiddenxcomkeys guard, allowing an authenticated API user with XCom write-and-read access to instantiate arbitrary airflow. classes ...

Missing Authorization

Overview Affected versions of this package are vulnerable to Missing Authorization in the POST /api/v2/assets/assetid/materialize endpoint and the XCom result check on waitdagrununtilfinished. An attacker can access and manipulate DAG runs and read XCom values belonging to other teams by supplyin...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the BaseXCom.deserializevalue. An attacker can execute arbitrary code on the API server by submitting specially crafted JSON string literals to the GET /api/v2/.../xcomEntries/key?deserialize=true...
