SCA: security update for apache-airflow (GHSA-j4jc-cq9h-xrhr)

high Tenable Cloud Security Plugin ID 472271

Description

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

 - Apache Airflow's Backfill API authorized a request against a Dag id supplied by the caller whenever the
 `backfill_id` path segment failed to parse. The authorization dependency parsed it with `int()` while the
 route handler parsed it as pydantic's `NonNegativeInt`, which accepts values `int()` rejects (`1.0`
 coerces to `1`); FastAPI resolves dependencies before endpoint validation, so the two acted on different
 Dags. An authenticated user holding edit permission on any single Dag could therefore read, pause and
 cancel backfills belonging to any other Dag, including moving another Dag's queued runs to `failed`. No
 non-default configuration is required and backfill ids are sequential, so finding a target is trivial.
 Users are advised to upgrade to apache-airflow 3.3.1 or later, which parses the backfill id with the same
 type the routes declare. (CVE-2026-68968)

Solution

Update the apache-airflow library and its related packages to version 3.3.1 or later.
