PYSEC-2026-2358 Apache Airflow: Execution API JWT leaked via KubernetesExecutor worker command-line args

A bug in Apache Airflow's KubernetesExecutor caused JWT tokens used by worker pods to authenticate against the Execution API to be passed to the worker container as command-line arguments visible in the pod spec. An authenticated UI/API user with Kubernetes read-only access to the cluster e.g...

PYSEC-2026-2349 Apache Airflow has an Improper Authorization issue

The structuredata endpoint in the Airflow UI returned external dependency graph nodes for linked Dags without checking whether the caller had read permission on those linked Dags. An authenticated UI/API user authorized for one Dag could enumerate linked Dag IDs and dependency metadata for other...

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...

PYSEC-2026-2368 Apache Airflow missing Certificate Validation

Apache Airflow SMTP Provider before 1.3.0, Apache Airflow IMAP Provider before 3.3.0, and Apache Airflow before 2.7.0 are affected by the Validation of OpenSSL Certificate vulnerability. The default SSL context with SSL library did not check a server's X.509 certificate. Instead, the code accepte...

BIT-AIRFLOW-2026-49296 Apache Airflow: Per-DAG read bypass discloses co-located DAGs' source via GET /api/v2/dagSources/{dag_id}

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...

BIT-AIRFLOW-2026-33264 Apache Airflow: DAG author RCE on webserver via unrestricted import_string() in BaseSerialization.deserialize()

A bug in BaseSerialization.deserialize allowed unrestricted importstring of attacker-controlled class paths when the Scheduler / API Server loaded a serialized DAG: a DAG author could embed a malicious trigger into a DAG to gain remote code execution on the API Server / Scheduler process, crossin...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the BaseSerialization.deserialize process. An attacker can execute arbitrary code on the API Server or Scheduler by embedding a malicious trigger into a serialized DAG, which is then deserialized and...

Improper Removal of Sensitive Information Before Storage or Transfer

Overview Affected versions of this package are vulnerable to Improper Removal of Sensitive Information Before Storage or Transfer in the Bulk Variables API due to the redact function being called without the variable key, which prevents the shouldhidevalueforkey check from triggering on...

Authorization Bypass Through User-Controlled Key

Overview Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key via the GET /api/v2/dagSources/dagid endpoint, which returns the entire source file containing multiple DAGs without redacting those the user is not authorized to access. An attacker can...

Improper Removal of Sensitive Information Before Storage or Transfer

Overview Affected versions of this package are vulnerable to Improper Removal of Sensitive Information Before Storage or Transfer in the REST API task-instance detail and list endpoints, which returned deferred task trigger keyword arguments without masking sensitive data. An attacker can access...

PYSEC-2026-2087

The Config API in Apache Airflow surfaced per-key secrets-backend overrides environment variables like AIRFLOWSECRETSBACKENDKWARGSECRETID and AIRFLOWWORKERSSECRETSBACKENDKWARGSECRETID as synthetic config options whose option names were not in sensitiveconfigvalues, so the masker did not redact...
