SCA: security update for shell-quote (GHSA-g4rg-993r-mgx7)

critical Tenable Self-Hosted Container Security Plugin ID 414870

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject
 unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of
 this package is passed to a real shell as a quoted argument to a command with exec(), an attacker can
 inject arbitrary commands. This is because the Windows drive letter regex character class is {A-z] instead
 of the correct {A-Za-z]. Several shell metacharacters exist in the space between capital letter Z and
 lower case letter a, such as the backtick character. (CVE-2021-42740)
