Chainguard: airflow-core-2: security update to 2.11.2-r13

high Tenable Cloud Security Plugin ID 473608

Description

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

 - fsspec is a specification and Python implementation framework for filesystem interfaces. From 0.9.0 until
 2026.6.0, fsspec.implementations.reference.ReferenceFileSystem evaluates fields from Kerchunk reference
 JSON documents through unrestricted jinja2.Template(...).render(...) calls in
 _process_references1._render_jinja, _process_templates, and _process_gen in
 fsspec/implementations/reference.py. A document supplied inline or fetched from an attacker-controlled URL
 can provide template expressions that execute Python code when the reference filesystem is opened,
 including through consumers such as xarray, before referenced data is read. The _process_gen path is
 reached whenever a document includes a gen array, while the other paths depend on template-related options
 and values. This issue is fixed in version 2026.6.0. (CVE-2026-104851)

Solution

Update the airflow-core-2 library and its related packages to version 2.11.2-r13 or later.
