Browserify version 2.13.2 represents a minor update to the widely used JavaScript module bundler, building upon the foundation laid by its predecessor, version 2.13.1. Both versions share the same core purpose: enabling Node.js-style require() statements to function seamlessly within web browsers. This is achieved by traversing and analyzing project dependencies, consolidating them into a single, browser-compatible file. Developers leveraging Browserify can readily structure their client-side code using familiar modular patterns, enhancing maintainability and organization, similar to backend development practices.
Examining the provided data reveals that the core dependencies and development dependencies remain unchanged between version 2.13.1 and 2.13.2. Packages like umd, through, optimist, and module-deps continue to underpin the functionality, handling tasks ranging from universal module definition support to stream processing and dependency management. Similarly, the development environment, geared towards testing and contribution, utilizes packages like tap, dnode, and coffee-script consistently across both versions. The key distinguishing factor lies in the releaseDate, indicating that version 2.13.2 was published shortly after 2.13.1, suggesting an immediate bug fix, optimization, or very minor feature addition that didn't necessitate altering dependency versions. For developers deciding whether to upgrade, while the core functionality is expected to be identical, upgrading to 2.13.2 is recommended to benefit from any potential stability improvements or fixes introduced in the newer release. The MIT license and author details remain consistent, solidifying the package's open-source credentials and maintainer information. Consider the newer version as a refinement of the already sound foundation.
All the vulnerabilities related to the version 2.13.2 of the package
Incorrect Handling of Non-Boolean Comparisons During Minification in uglify-js
Versions of uglify-js prior to 2.4.24 are affected by a vulnerability which may cause crafted JavaScript to have altered functionality after minification.
Upgrade UglifyJS to version >= 2.4.24.
Regular Expression Denial of Service in uglify-js
Versions of uglify-js prior to 2.6.0 are affected by a regular expression denial of service vulnerability when malicious inputs are passed into the parse() method.
var u = require('uglify-js');
var genstr = function (len, chr) {
var result = "";
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
u.parse("var a = " + genstr(process.argv[2], "1") + ".1ee7;");

Potential Command Injection in shell-quote
Affected versions of shell-quote do not properly escape command line arguments, which may result in command injection if the library is used to escape user input destined for use as command line arguments.
The following characters are not escaped properly: >,;,{,}
Bash has a neat but not well known feature known as "Bash Brace Expansion", wherein a sub-command can be executed without spaces by running it between a set of {} and using the , instead of to seperate arguments. Because of this, full command injection is possible even though it was initially thought to be impossible.
const quote = require('shell-quote').quote;
console.log(quote(['a;{echo,test,123,234}']));
// Actual "a;{echo,test,123,234}"
// Expected "a\;\{echo,test,123,234\}"
// Functional Equivalent "a; echo 'test' '123' '1234'"
Update to version 1.6.1 or later.
Improper Neutralization of Special Elements used in a Command in Shell-quote
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.
Potential for Script Injection in syntax-error
Versions of syntax-error prior to 1.1.1 are affected by a cross-site scripting vulnerability which may allow a malicious file to execute code when browserified.
Update to version 1.1.1 or later.
