Vue version 2.1.4 is a minor update following version 2.1.3 in the popular Vue.js framework, a reactive, component-oriented view layer designed for crafting modern web interfaces. While the core description and functionalities remain consistent between these two versions, inspecting the package.json reveals subtle differences in their release dates and potentially internal dependency management, though the listed devDependencies appear identical.
For developers, this suggests a stable and incremental improvement. The absence of changes in listed dependencies points towards bug fixes, performance enhancements, or internal refactoring without introducing breaking changes or requiring updates to the developer's existing toolchain. Existing projects using Vue 2.1.3 can likely upgrade to 2.1.4 with minimal risk and effort, potentially benefiting from subtle refinements.
While the provided data doesn't explicitly detail the specific improvements in 2.1.4, developers are encouraged to consult the official Vue.js changelog or release notes for a comprehensive understanding of the changes. Upgrading to the latest minor version within a stable release line, like from 2.1.3 to 2.1.4, generally ensures access to the most up-to-date bug fixes, performance optimizations, and security patches, solidifying the reliability and robustness of their Vue.js applications. Remember to run thorough testing to guarantee compatibility of your code.
All the vulnerabilities related to the version 2.1.4 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.
