Webpack version 0.4.9 arrived in June 2012, a little over a month after its predecessor, version 0.4.8. Both serve as bundlers for CommonJs modules for front-end development, allowing developers to split codebases into manageable bundles for on-demand loading, crucial for improving website performance and user experience. Each supports a wide array of file types right out of the box; like JavaScript, JSON, Jade, CoffeeScript, and CSS. They can be extended using custom loaders.
A key area of interest for developers lies in the package's dependencies. Both versions share an identical dependency list, including crucial packages like esprima for JavaScript parsing, sprintf for string formatting, optimist for command-line argument parsing, and uglify-js for code minification. They rely on various loaders (css-loader, raw-loader, val-loader, file-loader, jade-loader, json-loader, less-loader, style-loader, bundle-loader, coffee-loader, script-loader) to process different file types which shows the breadth of its capabilities.
The development dependencies of mocha and should indicate a clear commitment to testing and quality assurance. The releases differ primarily in their release dates, suggesting any differences were likely focused on bug fixes, minor enhancements, or performance improvements that didn't necessitate changes to the core dependency set. Developers updating from 0.4.8 to 0.4.9 would primarily benefit from stability and incremental improvements, ensuring a smoother bundling process.
All the vulnerabilities related to the version 0.4.9 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;");

Update to version 2.6.0 or later.
Regular Expression Denial of Service in clean-css
Version of clean-css prior to 4.1.11 are vulnerable to Regular Expression Denial of Service (ReDoS). Untrusted input may cause catastrophic backtracking while matching regular expressions. This can cause the application to be unresponsive leading to Denial of Service.
Upgrade to version 4.1.11 or higher.
Sandbox Bypass Leading to Arbitrary Code Execution in constantinople
Versions of constantinople prior to 3.1.1 are vulnerable to a sandbox bypass which can lead to arbitrary code execution.
Update to version 3.1.1 or later.
