Vue.js version 2.3.2 represents a minor update to the popular JavaScript framework, building upon version 2.3.1. Both versions share the same core description: a reactive, component-oriented view layer designed for crafting modern web interfaces. This means developers will experience a familiar environment for building user interfaces with reusable components and a reactive data binding system that simplifies state management.
A key area of interest for developers is the devDependencies section. A comparison between versions 2.3.1 and 2.3.2 reveals that the devDependencies are identical. This suggests that the changes are small bug fixes and incremental patches rather than significant updates to the build process or testing environment. This suggests the update from version 2.3.1 to version 2.3.2 is a stable upgrade, ensuring compatibility with existing tools and workflows. Developers can seamlessly transition to the newer version without the need for extensive reconfigurations or code modifications.
Both versions maintain the same licensing (MIT), repository location, and author (Evan You), further emphasizing their close relationship. The "releaseDate" differs between the two versions as version 2.3.1 came out a few hours before version 2.3.2. This hints that version 2.3.2 could be fixing something important for the build process. Developers looking for long-term stability and incremental improvements will find both versions of Vue.js 2.3 well suited for their projects, offering a solid foundation for creating dynamic and interactive web applications.
All the vulnerabilities related to the version 2.3.2 of the package
ReDoS vulnerability in vue package that is exploitable through inefficient regex evaluation in the parseHTML function
The ReDoS can be exploited through the parseHTML function in the html-parser.ts file. This flaw allows attackers to slow down the application by providing specially crafted input that causes inefficient processing of regular expressions, leading to excessive resource consumption.
To demonstrate this vulnerability, here's an example. In a Vue client-side application, create a new Vue instance with a template string that includes a <script> tag but closes it incorrectly with something like </textarea>.
new Vue({
el: '#app',
template: '
<div>
Hello, world!
<script>${'<'.repeat(1000000)}</textarea>
</div>'
});
Next, set up a basic HTML page (e.g., index.html) to load this JavaScript and mount the Vue instance:
<!DOCTYPE html>
<html>
<head>
<title>My first Vue app</title>
</head>
<body>
<div id=\"app\">Loading...</div>
</body>
</html>
When you visit the app in your browser at http://localhost:3000, you'll notice that the time taken to parse and mount the Vue application increases significantly due to the ReDoS vulnerability, demonstrating how the flaw can affect performance.
