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)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

(CVE-2026-104851)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote openSUSE 16 host has a package installed that is affected by a vulnerability as referenced in the openSUSE- SU-2026:22028-1 advisory.

    Changes in python-fsspec:

    - CVE-2026-104851: python-fsspec: remote code execution via       server-side template injection in `ReferenceFileSystem` (bsc#1284173)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
