CVE-2026-38743

The authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop HITL and TaskInstance records: a logged-in Airflow user with read access to at least one DAG could retrieve HITL prompts including their request parameters and full TaskInstance details for DA...

CVE-2026-45426

Exploitation requires the attacker to already be an authenticated Airflow worker holding a valid Log-server JWT issued for at least one Dag. Apache Airflow's Log server authorized JWT tokens against Dag IDs by applying Python's str.lstrip to the requested path segment when verifying the JWT's sub...

CVE-2026-33858

Dag Authors, who normally should not be able to execute code in the webserver context could craft XCom payload causing the webserver to execute arbitrary code. Since Dag Authors are already highly trusted, severity of this issue is Low. Users are recommended to upgrade to Apache Airflow 3.2.0,...

BIT-AIRFLOW-2026-46764 Apache Airflow: Event Log detail endpoint bypasses DAG-scoped event log permission filter

The Event Log detail endpoint GET /api/v2/eventLogs/eventlogid in Apache Airflow fetched audit-log rows directly by numeric ID after only the generic Audit Log permission check, while the collection endpoint GET /api/v2/eventLogs applied per-Dag scoping. An authenticated UI/API user with audit-lo...

BIT-AIRFLOW-2026-45426 Apache Airflow: Log server JWT authorization bypass via Python lstrip() character stripping allows cross-Dag log access

Exploitation requires the attacker to already be an authenticated Airflow worker holding a valid Log-server JWT issued for at least one Dag. Apache Airflow's Log server authorized JWT tokens against Dag IDs by applying Python's str.lstrip to the requested path segment when verifying the JWT's sub...
