Vue 2.7.15 represents a refinement over its predecessor, Vue 2.7.14, offering subtle but crucial updates for developers leveraging this established framework. The core functionality remains consistent, focusing on reactive, component-oriented view layer development for modern web interfaces. The primary dependency, @vue/compiler-sfc, is updated to version 2.7.15, aligning the single-file component compiler with the main package, potentially including bug fixes or minor feature enhancements related to template compilation and component handling.
While the development dependencies largely overlap, version 2.7.15 upgrades vitest from 0.12.10 to 0.34.6 and karma-esbuild from 2.2.4 to 2.2.5. These changes likely involve improvements to the testing environment, potentially affecting test performance, stability, or compatibility with newer testing patterns. The dist information is also updated slightly, with file count decreasing by 1 and unpacked size increasing from 4491176 to 4497024 bytes.
For developers, the update to Vue 2.7.15 warrants consideration, especially those heavily invested in testing workflows using Vitest or relying on precise memory implications of their build deployment. While not a major feature release, the incremental changes ensure continued compatibility with the broader ecosystem of development tools and libraries, ensuring seamless integration and addressing minor issues around code size. Stay updated for optimized development experience.
All the vulnerabilities related to the version 2.7.15 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.
