Browserify is a powerful tool that allows developers to write Node.js-style modules that run in the browser. It essentially bundles all your dependencies into a single file, making it easier to manage complex JavaScript applications on the client side. Version 3.24.1 is a minor incremental update over version 3.24.0, both sharing the same core functionality and dependency structure, so the upgrade should be smooth. Both versions include key features like the ability to use require() in your browser code, a vast ecosystem of Node.js modules available for front-end development and transforms that allow you to preprocess your code, enabling features like JSX support and other language extensions.
The versions are virtually identical, sharing the same dependencies, development dependencies, license, repository information, and author details. The key difference lies only in the release date. Version 3.24.1 emerges just a couple of hours after 3.24.0 and the fixes are probably minimal. Both packages have a rich set of dependencies, including modules for URL parsing (url), utilities (util), assertions (assert), event handling (events), and stream manipulation (through, duplexer, stream-combiner, stream-browserify), among many others, to give you power when coding on the browser. Developers should feel safe when upgrading since it is only a matter of hours between the 2 publishes. Due to the lack of a changelog pointing to a fix or a specific improvement upgrading from 3.24.0 to 3.24.1 is probably not very important and will no add any real advantages.
All the vulnerabilities related to the version 3.24.1 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
sys 0m0.094s
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.
