Echo: apache-airflow: security update to 3.2.0

medium Tenable Cloud Security Plugin ID 458158

Description

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

 - Apache Airflow versions 3.0.0 through 3.1.8 DagRun wait endpoint returns XCom result values even to users
 who only have DAG Run read permissions, such as the Viewer role.This behavior conflicts with the FAB RBAC
 model, which treats XCom as a separate protected resource, and with the security model documentation that
 defines the Viewer role as read-only. Airflow uses the FAB Auth Manager to manage access control on a per-
 resource basis. The Viewer role is intended to be read-only by default, and the security model
 documentation defines Viewer users as those who can inspect DAGs without accessing sensitive execution
 results. Users are recommended to upgrade to Apache Airflow 3.2.0 which resolves this issue.
 (CVE-2026-34538)

Solution

Update the apache-airflow library and its related packages to version 3.2.0 or later.
