Overview
org.webjars.npm:shell-quote is a package used to quote and parse shell commands.
Affected versions of this package are vulnerable to Command Injection via the quote function when a { comment } token is followed by a string token containing a line terminator. A { comment } token emits a #-prefixed string that comments out the rest of the shell line, including the opening quote of any subsequent string token. A line terminator inside that subsequent string ends the comment, causing the remainder of the string to be interpreted as shell input - for example, quote(['echo', { comment: 'x' }, 'a\nid;#']) executes id in sh, bash, zsh, ksh, and dash. Because parse emits a comment token for a mid-word # (such as in a URL fragment), appending tokens to parse output is sufficient to reach the vulnerable code path.
