Vue 2.6.14 represents a subtle but important iteration over its predecessor, Vue 2.6.13, in the venerable Vue 2 series. Primarily, this new version includes essential fixes and minor improvements that enhance stability and developer experience. While the core functionalities remain largely unchanged, developers upgrading from Vue 2.6.13 can expect smoother operation, especially in edge cases or within specific build environments.
The dependency trees of both versions are virtually identical, indicating that the upgrade doesn't introduce any breaking changes related to the development toolchain. This consistency ensures a seamless transition for projects already leveraging Vue 2, minimizing the risk of compatibility issues. The devDependencies block lists popular tools and libraries that Vue relies on during development, contributing to its robust development ecosystem, among the packages are babel, webpack, and eslint, used to build, test and lint the javascript code.
From the perspective of developers, the key takeaway is that version 2.6.14 is a worthwhile upgrade offering ongoing support and refinement to the mature Vue 2 framework, ensuring continued reliability for existing applications and those still under development. This version delivers bug fixes that could impact stability of your applications. The slight increase in unpacked size may also hint at minor internal code updates, potentially related to those fixes or performance optimizations. The recent releaseDate highlights its position as the latest patch in the Vue 2 line.
All the vulnerabilities related to the version 2.6.14 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.
