"The version of nodejs / nodejs18 installed on the remote Azure Linux 3.0 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the CVE-2025-22150 advisory.

  - Undici is an HTTP/1.1 client. Starting in version 4.5.0 and prior to versions 5.28.5, 6.21.1, and 7.2.3,
    undici uses `Math.random()` to choose the boundary for a multipart/form-data request. It is known that the
    output of `Math.random()` can be predicted if several of its generated values are known. If there is a
    mechanism in an app that sends multipart requests to an attacker-controlled website, they can use this to
    leak the necessary values. Therefore, an attacker can tamper with the requests going to the backend APIs
    if certain conditions are met. This is fixed in versions 5.28.5, 6.21.1, and 7.2.3. As a workaround, do
    not issue multipart requests to attacker controlled servers. (CVE-2025-22150)

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