The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2024:5814 advisory.

* node-tar: denial of service while parsing a tar file due to lack of folders depth validation     (CVE-2024-28863)
* nodejs: Bypass network import restriction via data URL (CVE-2024-22020)
* nodejs: fs.lstat bypasses permission model (CVE-2024-22018)
* nodejs: fs.fchown/fchmod bypasses permission model (CVE-2024-36137)

Tenable has extracted the preceding description block directly from the AlmaLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
