Browserify, a cornerstone tool for front-end developers, allows you to use Node.js-style require() statements in browser-based JavaScript. Versions 10.2.5 and 10.2.6 are closely related, representing incremental improvements to this powerful library. A quick analysis reveals that the core dependencies and devDependencies remain virtually identical. This suggests that the update from 10.2.5 to 10.2.6 likely involves bug fixes, performance enhancements, or very minor feature adjustments, rather than a major overhaul of the codebase.
For developers, this means that upgrading from 10.2.5 to 10.2.6 should be relatively seamless. There's likely no need to rewrite code or refactor existing Browserify configurations. The consistent dependency list indicates that the fundamental functionality and API remain stable. To confirm this, developers should consult the Browserify changelog or release notes (typically available on the project's GitHub repository) for a detailed breakdown of the changes. Although the core dependencies of both versions are the same, you can see that the release dates are close to each other; therefore, version 10.2.6 is probably a bug fix of 10.2.5 version and it's important to upgrade to this version. When working with tools like Browserify, continuous integration pipelines, and automated testing are key to a smooth upgrade process. This version of Browserify packages your code for use in web browsers.
All the vulnerabilities related to the version 10.2.6 of the package
Regular Expression Denial of Service in minimatch
Affected versions of minimatch are vulnerable to regular expression denial of service attacks when user input is passed into the pattern argument of minimatch(path, pattern).
var minimatch = require(“minimatch”);
// utility function for generating long strings
var genstr = function (len, chr) {
var result = “”;
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
var exploit = “[!” + genstr(1000000, “\\”) + “A”;
// minimatch exploit.
console.log(“starting minimatch”);
minimatch(“foo”, exploit);
console.log(“finishing minimatch”);
Update to version 3.0.2 or later.
minimatch ReDoS vulnerability
A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.
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.
