"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-000165 advisory.

    An issue was discovered in the Multipart Request Parser in Django 3.2 before 3.2.18, 4.0 before 4.0.10,
    and 4.1 before 4.1.7. Passing certain inputs (e.g., an excessive number of parts) to multipart forms could
    result in too many open files or memory exhaustion, and provided a potential vector for a denial-of-
    service attack.

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

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