CVE-2026-49487 Apache Airflow: Task-instance API exposes secrets in deferred trigger kwargs

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. When a deferred operator passed a secret for example a provider API key into its trigger, any authenticated user with DAG-scoped task-instance read acces...

CVE-2026-48828

The Bulk Variables API in Apache Airflow fails to pass the variable's key to the redactor for JSON-decodable values. This causes the should_hide_value_for_key check to fail for keys ending in suffixes like *_password, *_token, or *_secret. Consequently, an authenticated user with bulk Variable re...

CVE-2026-48828 Apache Airflow: Bulk JSON Variables bypass should_hide_value_for_key - redact() called without the key

The Bulk Variables API in Apache Airflow called the redactor without passing the variable's key, so the key-based shouldhidevalueforkey check which triggers on secret-suffixed key names like password / token / secret could not fire for JSON-decodable variable values. An authenticated UI/API user...

CVE-2026-48891

A bug in Apache Airflow's /ui/dependencies scheduling graph endpoint applied the caller's readable-Dag filter to the top-level serialized Dag key but still emitted referenced Dag IDs through the dep.source and dep.target fields of trigger / sensor dependency entries.
