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

CVE ID :CVE-2026-49487

Published : July 7, 2026, 10:16 a.m. | 1 hour, 31 minutes ago

Description :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 access for
that DAG could read that secret in clear text while the task was deferred.
Users should upgrade to apache-airflow 3.3.0 or later, which masks sensitive
values in trigger kwargs returned by the API.

Severity: 0.0 | NA
