Vue version 2.5.10 is a minor release following 2.5.9 within the popular Vue.js framework, a progressive JavaScript framework for building user interfaces. Both versions share the same core description: a reactive, component-oriented view layer ideal for crafting modern web interfaces. The primary difference between the two lies in their release dates, with 2.5.10 being published on December 12, 2017, and 2.5.9 on November 27, 2017.
A closer inspection reveals identical development dependencies, encompassing a variety of tools used in the development, testing and build process. These include testing frameworks like Karma and Jasmine, linting tools like ESLint, module bundlers like Rollup and Webpack, and various Babel plugins for JSX and ES2015 support.
For developers, upgrading from 2.5.9 to 2.5.10 likely involves bug fixes and minor improvements rather than significant new features. While no specific bug fixes are listed, such minor version increments typically address edge cases, performance optimizations, and resolutions to community-reported issues that enhance overall stability.
Users considering either version can be assured of a robust set of development tools and a well-established ecosystem. Due to the almost identical nature of these releases, the choice between them is generally negligible; however, it is almost always a better idea to upgrade to the newest bug-fixed version. Therefore opting for 2.5.10 ensures access to the most up-to-date refinements. Ultimately, both versions support modern web development practices and provide a solid foundation for building interactive and dynamic web applications.
All the vulnerabilities related to the version 2.5.10 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.
