Echo: apache-airflow: security update to 3.2.1rc1

medium Tenable Self-Hosted Container Security Plugin ID 464385

Description

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

 - The authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop
 (HITL) and TaskInstance records: a logged-in Airflow user with read access to at least one DAG could
 retrieve HITL prompts (including their request parameters) and full TaskInstance details for DAGs outside
 their authorized scope. Because HITL prompts and TaskInstance fields routinely carry operator parameters
 and free-form context attached to a task, the leak widens visibility of DAG-run data beyond the intended
 per-DAG RBAC boundary for every authenticated user. Users are recommended to upgrade to version 3.2.1 ,
 which fixes this issue. (CVE-2026-38743)

Solution

Update the apache-airflow library and its related packages to version 3.2.1rc1 or later.
