Browserify is a powerful tool that allows developers to write Node.js-style modules that run in the browser by bundling dependencies. Comparing versions 3.11.1 and 3.11.0, while seemingly minor, reveals subtle enhancements. Both versions offer the core functionality of browser-side require(), enabling modular JavaScript development for web applications. Key dependencies like umd, url, util, assert, events and others responsible for core functionalities remain consistent, ensuring stability in fundamental module handling. The development dependencies like "seq", "tap", "dnode", "mkdirp", "backbone", "coffee-script" also remained constant.
A notable aspect for developers considering either version is the comprehensive list of dependencies, many dedicated to browser-specific implementations of Node.js core modules. Modules like http-browserify, crypto-browserify, stream-browserify, and zlib-browserify are crucial for replicating Node.js functionality within the browser environment. While the dependency lists appear identical, the release dates differ by approximately 33 minutes. Although the change log of the package provides more specific and detailed insights in the changes done, but in this particular case there were no changes in the code or the dependencies, so the update was probably only in the metadata of the package itself, such as the published date.
For developers seeking a reliable browserify version for modular JavaScript development, both 3.11.0 and 3.11.1 offer a solid foundation. The later version include only metadata updates.
All the vulnerabilities related to the version 3.11.1 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;");
$ time node test.js 10000

$ time node test.js 80000
real 0m6.486s
user 0m6.229s

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.
