Hi,

The following vulnerability was published for node-shell-quote.

CVE-2021-42740[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
