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

  - ** DISPUTED ** 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. NOTE: The npm team believes this is
    not a vulnerability. It would require someone to socially engineer package.json which has different
    dependencies than package-lock.json. That user would have to have file system or write access to change
    dependencies. The npm team states preventing malicious actors from socially engineering or gaining file
    system access is outside the scope of the npm CLI. (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.");
