Vue version 2.7.10 is a patch release following the previous stable version 2.7.9, both iterations of this popular JavaScript framework maintaining its core focus on building reactive, component-oriented user interfaces for the modern web. The primary distinction between these releases lies in their minor version number, indicating that version 2.7.10 likely incorporates bug fixes, performance improvements, or other minor enhancements without introducing breaking changes to the API.
For developers already using Vue 2.7.9, upgrading to version 2.7.10 should be a straightforward process. Given the nearly identical devDependencies like rollup, typescript and @microsoft/api-extractor, the tooling ecosystem remains consistent. The dependencies field shows only a change in the specific version of @vue/compiler-sfc which suggests targeted updates to the single-file component compiler process. The slight increase in unpackedSize from 4551164 to 4552699 bytes could be attributed to these targeted component compiler enhancements and bug fixes.
The MIT license ensures developers have the freedom to use and modify Vue in a variety of projects. The package's continued availability on npm and its active development confirm Vue's position as a mature and reliable choice for web developers. Always consult the official Vue changelog for a comprehensive list of changes in each patch release for detailed information on specific fixes and improvements.
All the vulnerabilities related to the version 2.7.10 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.
