"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-2024-22020 advisory.

  - A security flaw in Node.js allows a bypass of network import restrictions. By embedding non-network
    imports in data URLs, an attacker can execute arbitrary code, compromising system security. Verified on
    various platforms, the vulnerability is mitigated by forbidding data URLs in network imports. Exploiting
    this flaw can violate network import security, posing a risk to developers and servers. (CVE-2024-22020)

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