Apache Airflow's /assets/events API returned asset events for every Dag in the deployment, with no filter restricting them to the Dags the caller is authorized to read. Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID,...

CVE-2026-75158 Apache Airflow: Assets events API returns asset events for every Dag with no per-Dag authorization filter

Apache Airflow's /assets/events API returned asset events for every Dag in the deployment, with no filter restricting them to the Dags the caller is authorized to read. Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID,...

PT-2026-96119

Name of the Vulnerable Software and Affected Versions Apache Airflow versions prior to 3.3.2 Description The /assets/events API endpoint fails to restrict asset events to the Dags that the caller is authorized to read. Authenticated users with asset-read access can enumerate asset events for Dags...

Interpretation Conflict

Overview Affected versions of this package are vulnerable to Interpretation Conflict due to inconsistent parsing of the backfillid path segment between the authorization dependency and the route handler. An attacker can gain unauthorized access to read, pause, and cancel backfills for other Dags,...

Name of the Vulnerable Software and Affected Versions Apache Airflow versions prior to 3.3.1 Description In deployments using multi-team mode with a team-aware auth manager, the asset materialization endpoint POST /api/v2/assets/asset id/materialize and the XCom result check on wait dag run until...

CVE-2026-59245

In the Apache Airflow FAB auth manager, a DAG whose dagid is DAGs collided with the global all-DAGs permission resource name produced by resourcename, so a user granted per-DAG accesscontrol on that one DAG was silently granted the global all-DAGs permission privilege escalation. The escalation...

CVE-2026-59245 Apache Airflow FAB provider: FAB auth manager: a DAG named "DAGs" hijacks the global all-DAGs permission (access_control privilege escalation via resource_name() collision)

In the Apache Airflow FAB auth manager, a DAG whose dagid is DAGs collided with the global all-DAGs permission resource name produced by resourcename, so a user granted per-DAG accesscontrol on that one DAG was silently granted the global all-DAGs permission privilege escalation. The escalation...

CVE-2026-59245

The CVE affects Apache Airflow FAB provider: FAB auth manager. A DAG with dag_id/DAGs collides with the global all-DAGs permission name produced by resource_name(), causing a per-DAG access_control grant on that DAG to silently confer the global all-DAGs permission. This yields privilege escalati...

PYSEC-2026-2351 Apache Airflow's authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop (HITL) and TaskInstance record

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...

PYSEC-2026-2360 Apache Airflow allows users with asset materialize permissions to trigger DAGs outside of their permissions

UI / API User with asset materialize permission could trigger dags they had no access to. Users are advised to migrate to Airflow version 3.2.0 that fixes the issue...

GHSA-4FH7-7JX4-8F6C apache-airflow DAG source authorization bypass exposes co-located DAG source

Before apache-airflow 3.3.0, a user authorized to read one Dag could disclose the source of other Dags co-located in the same source file. GET /api/v2/dagSources/dagid — and the equivalent Dag-source view in the UI — returned the entire source file without redacting Dags the caller was not...

EUVD-2026-42029

In Apache Airflow before 3.3.0, the REST API task-instance detail and list endpoints returned a deferred task's trigger kwargs without masking.

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...

BIT-AIRFLOW-2026-41014 Apache Airflow: per-DAG RBAC bypass on /ui/partitioned_dag_runs endpoints

The partitioneddagruns endpoints in the Airflow UI enforced only asset-level access control, not per-Dag authorization. An authenticated UI/API user with global Asset:read permission could enumerate partition run state, schedule configuration, and asset wiring for Dags they were not authorized to...
