Echo: apache-airflow: security update to 3.3.0

medium Tenable Cloud Security Plugin ID 459673

Description

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

 - Before apache-airflow 3.3.0, a user authorized to read one Dag could disclose the source of other Dags co-
 located in the same source file. `GET /api/v2/dagSources/{dag_id}` — and the equivalent Dag-source view in
 the UI — returned the entire source file without redacting Dags the caller was not authorized to read,
 bypassing per-DAG read authorization. Deployments that co-locate multiple Dags in a single file and rely
 on per-DAG access control to limit source visibility are affected; single-Dag-per-file deployments are
 not. Upgrade to apache-airflow 3.3.0 or later. (CVE-2026-49296)

Solution

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