How to Prevent CSRF Attacks in a Vue.js Application with Axios and Vuex?
I'm stuck on something that should probably be simple. I'm working on a personal project and I'm stuck on something that should probably be simple... I'm building a Vue.js application using Axios for API requests and Vuex for state management. While implementing state changes that require authentication, I'm concerned about Cross-Site Request Forgery (CSRF) vulnerabilities. Currently, I'm sending requests to my backend API, but I haven't included any CSRF tokens in my requests. I've read that it's crucial to include them to prevent CSRF attacks, but I'm not sure how to integrate this with my current setup. Here’s a simplified version of my code for making authenticated requests: ```javascript import axios from 'axios'; import store from './store'; axios.defaults.baseURL = 'https://myapi.com'; export const fetchUserData = async () => { const token = store.state.auth.token; try { const response = await axios.get('/user/data', { headers: { 'Authorization': `Bearer ${token}` } }); return response.data; } catch (error) { console.error('Error fetching user data:', error); throw error; } }; ``` In this code, I’m only sending an authorization token in the headers. I’m worried that without a CSRF token, my app might be vulnerable. I've looked at using libraries like `csurf`, but I'm not sure how to generate and include the CSRF token in my Axios requests. Could anyone provide guidance on how to securely implement CSRF protection in my scenario? Additionally, if my backend is a Node.js/Express setup, how should I configure it to validate these CSRF tokens? I'm currently using Express version 4.17 and have the `cookie-parser` middleware integrated. Any suggestions or code examples would be greatly appreciated! My development environment is macOS. Am I missing something obvious? This is for a application running on CentOS. I'm working with Javascript in a Docker container on Ubuntu 20.04. I appreciate any insights!
