"The version of python-pillow installed on the remote host is prior to 2.0.0-23.gitd1c6db8. It is, therefore, affected by
a vulnerability as referenced in the ALAS2-2026-3180 advisory.

    Pillow is a Python imaging library. From 10.3.0 to before 12.1.1, n out-of-bounds write may be triggered
    when loading a specially crafted PSD image. This vulnerability is fixed in 12.1.1. (CVE-2026-25990)

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

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