"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-822 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)

    With the aid of the diagnostics_channel utility, an event can be hooked into whenever a worker thread is
    created. This is not limited only to workers but also exposes internal workers, where an instance of them
    can be fetched, and its constructor can be grabbed and reinstated for malicious usage.This vulnerability
    affects Permission Model users (--permission) on Node.js v20, v22, and v23. (CVE-2025-23083)

    A memory leak could occur when a remote peer abruptly closes the socket without sending a GOAWAY
    notification. Additionally, if an invalid header was detected by nghttp2, causing the connection to be
    terminated by the peer, the same leak was triggered. This flaw could lead to increased memory consumption
    and potential denial of service under certain conditions. (CVE-2025-23085)

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

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