Browserify is a powerful tool for developers looking to write modular JavaScript for the browser, enabling them to use Node.js-style require() statements in their client-side code. Versions 3.4.0 and 3.4.1 are closely related, with 3.4.1 released just two days after 3.4.0, suggesting a quick patch or minor adjustment. Examining the dependencies reveals the key difference: the assert dependency. Version 3.4.0 relies on assert with a caret version range ~1.0.0, while 3.4.1 uses a specific git archive URL for assert https://github.com/substack/commonjs-assert/archive/1.0.0-float.tar.gz, and querystring is also managed through archive URL, specifying querystring":"https://github.com/substack/querystring/archive/0.2.0-ie8.tar.gz". This indicates a change to the way the assert module is resolved, potentially addressing a bug or ensuring compatibility. Also timers-browserify is managed using an archive URL.
For developers, this subtle change matters. If you encountered issues with assert or querystring in version 3.4.0, upgrading to 3.4.1 might resolve them. The shift to a direct git archive suggests a controlled dependency management strategy by the Browserify maintainers. Both versions share the same core dependencies and development dependencies, licensed under MIT, making them suitable for various projects. The release dates provide context for when these versions were relevant. The author information remains consistent, pointing to James Halliday (substack) as the driving force behind the project. Overall, users should check 3.4.1 release due to a possible problem addressed in the assert dependency.
All the vulnerabilities related to the version 3.4.1 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.
