Browserify is a powerful tool aimed at developers who want to utilize the Node.js require() methodology within browser-based projects. This package enables the consolidation of server-side code modules and their dependencies into a single file optimized for browser consumption. Examining versions 2.12.5 and 2.13.0 reveals a notable similarity in core functionality, boasting the same "browser-side require() the node way" description, dependencies and devDependencies. Both iterations rely on key modules such as umd, through, duplexer, and inherits for stream handling, object inheritance, and universal module definition, confirming their shared architecture. They even share the same author and MIT License.
However, the crucial difference lies in the releaseDate. Version 2.13.0 was published shortly after version 2.12.5, with the former a few minutes later than the latter. While the package manifests appear identical at first glance, this release timing difference implies a subtle update, perhaps addressing minor bug fixes, optimizations, or security patches within the dependent packages that didn't necessitate a change in dependencies. For developers, especially those prioritizing stability and receiving the updates, it's essential to consider the timing to ensure they are leveraging the most current and potentially improved version of Browserify to achieve optimal compatibility and performance in their browser-based applications, making the development process smoother and more efficient.
All the vulnerabilities related to the version 2.13.0 of the package
Incorrect Handling of Non-Boolean Comparisons During Minification in uglify-js
Versions of uglify-js
prior to 2.4.24 are affected by a vulnerability which may cause crafted JavaScript to have altered functionality after minification.
Upgrade UglifyJS to version >= 2.4.24.
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;");

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.
Improper Neutralization of Special Elements used in a Command in Shell-quote
The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of this package is passed to a real shell as a quoted argument to a command with exec()
, an attacker can inject arbitrary commands. This is because the Windows drive letter regex character class is [A-z]
instead of the correct [A-Za-z]
. Several shell metacharacters exist in the space between capital letter Z and lower case letter a, such as the backtick character.
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.
