Browserify is a powerful tool designed to let you use Node.js-style modules in the browser, making front-end development more modular and organized. Versions 3.14.0 and 3.14.1 are very similar, but understanding the subtle differences can be crucial for a smooth development experience. Both versions share the same core dependencies including umd, url, util, assert and many other modules necessary for emulating a Node.js environment in the browser. This allows developers to leverage familiar Node.js patterns and libraries directly within their browser-based applications.
A key detail for developers is the releaseDate. Version 3.14.1 was released on December 23, 2013, just a day after version 3.14.0. While the change is minor, updates often include bug fixes or small improvements, so developers who need the most stable experience will want to use the newest version. The dependencies and devDependencies sections can aid developers in understanding the tool's capabilities and integrating it within their setup, potentially saving them from troubleshooting compatibility issues by pointing them at specific versions of the dependencies it needs. To summarize, while the changes between 3.14.0 and 3.14.1 might be minor, staying up-to-date with the latest patch version ensures you're benefiting from any improvements or fixes.
All the vulnerabilities related to the version 3.14.1 of the package
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;");

Update to version 2.6.0 or later.
Prototype Pollution in minimist
Affected versions of minimist are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.
Upgrade to versions 0.2.1, 1.2.3 or later.
Prototype Pollution in minimist
Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
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.
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.
