Vulnerability	Vulnerable Version
H Remote Code Execution (RCE) shell-quote is a package used to quote and parse shell commands. Affected versions of this package are vulnerable to Remote Code Execution (RCE). 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. How to fix Remote Code Execution (RCE)? Upgrade `shell-quote` to version 1.7.3 or higher.	<1.7.3
