Vue 2.5.14 is a minor update to the popular JavaScript framework, building upon the solid foundation of Vue 2.5.13. While the core focus remains the same – providing a reactive, component-oriented view layer for building modern web interfaces – several dependency updates and internal improvements distinguish the two versions.
A key change lies in the updated development dependencies. Notably, buble transitions from version 0.18.0 to 0.19.3, and karma jumps from 1.7.0 to 2.0.0 signifying underlying enhancement. Webpack also sees an update from version 3.10.0 to 3.11.0, potentially optimizing the build process and improving module handling. These updates contribute to a more streamlined development experience and potentially improve performance of Vue applications.
Furthermore, the rollup-plugin-commonjs dependency is downgraded from 8.0.2 to version 8.0.0, but this is likely a minor adjustment to ensure compatibility and stability within the build pipeline. Several development dependencies are bumped to the latest versions, including typescript,shelljs and http-server.
While many developers might not directly interact with these development dependencies, their updates indirectly impact the library's robustness and efficiency. Ultimately, version 2.5.14 offers a refined and more stable Vue experience, incorporating incremental improvements that contribute to a better developer workflow and potentially enhanced application performance. The newer release date also indicates inclusion of recent security patches.
All the vulnerabilities related to the version 2.5.14 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.
