Echo: apache-airflow: security update to 3.3.0

medium Tenable Self-Hosted Container Security Plugin ID 464287

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-49487)

Solution

Update the apache-airflow library and its related packages to version 3.3.0 or later.
