Browserify is a powerful tool for developers who want to write Node.js-style modules for the browser. It allows you to use require() in your front-end code, making it easier to organize and manage your JavaScript projects. Looking at versions 3.23.1 and 3.24.0, both share the same core functionality and dependencies. Both versions come equipped with a wide array of dependencies covering everything from URL parsing (url) and utilities (util) to stream manipulation (through, duplexer) and browser-specific shims for core Node.js modules like http, https, and crypto. This extensive list showcases Browserify's commitment to providing a comprehensive environment for browser-based development using Node.js principles.
However, upgrading to version 3.24.0 offers the latest improvements and bug fixes, ensuring a more stable and reliable development experience. Crucially, while the codebases seem generally aligned, even minor version bumps can introduce internal optimizations that can lead to better performance or compatibility. Because the dependencies are identical, the improvements may lie somewhere in the internals of browserify itself or due to upgrades made on existing tools used, like vm-browserify or tty-browserify. Keeping up-to-date is the best way to guarantee you are taking advantage of the most recent benefits. Furthermore, staying current makes it easier to integrate new modules into front-end projects because it is an active and fully supported project focused on compatibility, features, and ease of use.
All the vulnerabilities related to the version 3.24.0 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;");

$ time node test.js 80000
real 0m6.486s

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.
