"The remote Fedora 37 host has packages installed that are affected by multiple vulnerabilities as referenced in the
FEDORA-2023-18476abd7e advisory.

  - The use of `Module._load()` can bypass the policy mechanism and require modules outside of the policy.json
    definition for a given module. This vulnerability affects all users using the experimental policy
    mechanism in all active release lines: 16.x, 18.x and, 20.x. Please note that at the time this CVE was
    issued, the policy is an experimental feature of Node.js. (CVE-2023-32002)

  - `fs.mkdtemp()` and `fs.mkdtempSync()` can be used to bypass the permission model check using a path
    traversal attack. This flaw arises from a missing check in the fs.mkdtemp() API and the impact is a
    malicious actor could create an arbitrary directory. This vulnerability affects all users using the
    experimental permission model in Node.js 20. Please note that at the time this CVE was issued, the
    permission model is an experimental feature of Node.js. (CVE-2023-32003)

  - A vulnerability has been discovered in Node.js version 20, specifically within the experimental permission
    model. This flaw relates to improper handling of Buffers in file system APIs causing a traversal path to
    bypass when verifying file permissions. This vulnerability affects all users using the experimental
    permission model in Node.js 20. Please note that at the time this CVE was issued, the permission model is
    an experimental feature of Node.js. (CVE-2023-32004)

  - A vulnerability has been identified in Node.js version 20, affecting users of the experimental permission
    model when the --allow-fs-read flag is used with a non-* argument. This flaw arises from an inadequate
    permission model that fails to restrict file stats through the `fs.statfs` API. As a result, malicious
    actors can retrieve stats from files that they do not have explicit read access to. This vulnerability
    affects all users using the experimental permission model in Node.js 20. Please note that at the time this
    CVE was issued, the permission model is an experimental feature of Node.js. (CVE-2023-32005)

  - The use of `module.constructor.createRequire()` can bypass the policy mechanism and require modules
    outside of the policy.json definition for a given module. This vulnerability affects all users using the
    experimental policy mechanism in all active release lines: 16.x, 18.x, and, 20.x. Please note that at the
    time this CVE was issued, the policy is an experimental feature of Node.js. (CVE-2023-32006)

  - The use of the deprecated API `process.binding()` can bypass the permission model through path traversal.
    This vulnerability affects all users using the experimental permission model in Node.js 20.x. Please note
    that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
    (CVE-2023-32558)

  - A privilege escalation vulnerability exists in the experimental policy mechanism in all active release
    lines: 16.x, 18.x and, 20.x. The use of the deprecated API `process.binding()` can bypass the policy
    mechanism by requiring internal modules and eventually take advantage of `process.binding('spawn_sync')`
    run arbitrary code, outside of the limits defined in a `policy.json` file. Please note that at the time
    this CVE was issued, the policy is an experimental feature of Node.js. (CVE-2023-32559)
