"The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.6:CLSA-2026:1772617597 advisory.

  - Maliciously crafted export names in an imported WebAssembly module can inject JavaScript code. The
    injected code may be able to access data and functions that the WebAssembly module itself does not have
    access to, similar to as if the WebAssembly module was a JavaScript module. This vulnerability affects
    users of any active release line of Node.js. The vulnerable feature is only available if Node.js is
    started with the `--experimental-wasm-modules` command line option. (CVE-2023-39333)

  - 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 these issues but has instead relied only on the application's self-reported version
number.");
