"The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the
ALSA-2022:4796 advisory.

  - The npm ci command in npm 7.x and 8.x through 8.1.3 proceeds with an installation even if dependency
    information in package-lock.json differs from package.json. This behavior is inconsistent with the
    documentation, and makes it easier for attackers to install malware that was supposed to have been blocked
    by an exact version match requirement in package-lock.json. (CVE-2021-43616)

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