Vue 2.6.10 is a minor patch release following version 2.6.9 of the popular JavaScript framework for building user interfaces. Both versions share the same core description: a reactive, component-oriented view layer ideal for crafting modern web applications. Examining the devDependencies, the list appears identical, indicating no new dependencies or updates to existing build tooling or testing libraries between these releases. Developers relying on specific versions of tools like Webpack, Rollup, Babel, or ESLint can expect consistent behavior across both versions.
Key differentiating factors lie in the details of the release. Vue 2.6.10 was released on March 20, 2019, a week after Vue 2.6.9, released on March 14, 2019. The newer version exhibits a slightly increased unpacked size (2974862 bytes compared to 2969595 bytes), suggesting minor code changes, bug fixes, or optimizations likely implemented between the two versions. It's typical for patch releases like this to contain internal tweaks, documentation updates, or resolutions to edge-case bugs reported by the community.
Developers should always consult the official Vue.js changelog or release notes for a comprehensive list of specific changes introduced in Vue 2.6.10 compared to 2.6.9. These resources usually outline the particular bug fixes, performance improvements, and any potential breaking changes (though unlikely in a patch release) that may influence their upgrade decision. For most users, upgrading to Vue 2.6.10 would be a recommended step to benefit from the latest improvements and bug fixes as it provides the most stable and refined experience within the 2.6 series.
All the vulnerabilities related to the version 2.6.10 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.
