CVE-2026-49487
Last modified
CVE-2026-49487 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
