It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-210 advisory.

  • An untrusted search path vulnerability exists in Node.js. <19.6.1, <18.14.1, <16.19.1, and <14.21.3 that could allow an attacker to search and potentially load ICU data when running with elevated privileges.
    (CVE-2023-23920)

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