Linux Distros Unpatched Vulnerability : CVE-2026-106073

critical Nessus Plugin ID 370548

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - A flaw in Node.js Permission Model filesystem enforcement leaves fs.realpathSync() without the required read permission checks. This is an incomplete fix of CVE-2026-21715, which only covered fs.realpathSync.native(). As a result, code running under --permission with restricted --allow-fs-read can still use fs.realpathSync() to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories. This vulnerability affects Node.js 26.x, 24.x, and 22.x. Thank you, to 0xoroot for reporting this vulnerability and thank you RafaelGSS for fixing it. (CVE-2026-106073)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
