How to Fix CVE-2024-9506

To remediate this vulnerability, upgrade all affected Vue dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

vue fixed: 3.0.0-alpha.0 
npm install vue@3.0.0-alpha.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls vue

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-9506, inspect your project dependencies using npm:

npm ls vue

Analyze the terminal output to locate any version of Vue in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0-alpha.0), your application is affected.

Note: The npm ls vue command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Vue, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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>`. ```javascript 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: ```html <!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.
