Vue 2.7.11 represents a minor version update over its predecessor, Vue 2.7.10, offering refinements and potentially bug fixes within the established Vue 2 ecosystem. Both versions remain committed to providing a reactive, component-oriented view layer suitable for crafting sophisticated web interfaces. Developers leveraging Vue 2 will find a familiar and consistent experience between these releases.
Key differences primarily reside in the updated dependencies. For instance, rollup sees a bump from version 2.75.6 to 2.79.1, while rollup-plugin-typescript2 moves from version 0.31.2 to 0.32.0. The core @vue/compiler-sfc matches the main version and goes from 2.7.10 to 2.7.11 also typescript is updated from 4.7.3 to 4.8.4.These updates likely incorporate performance improvements, new features, or bug resolutions contributed by the respective dependency maintainers. Developers should consult the changelogs of these specific dependencies to fully understand the implications of these version bumps. While the core functionality of Vue remains consistent, developers should thoroughly test their applications after upgrading to ensure compatibility with these dependency updates. The unpacked size has also decreased from 4552699 to 4483052. Ultimately, version 2.7.11 provides a more refined and up-to-date Vue 2 experience, encouraging developers to stay current with the latest incremental improvements and dependency enhancements.
All the vulnerabilities related to the version 2.7.11 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.
