19-33: Critical: Fix token verification logic in root routeThe current implementation has several issues:
- The
tokenvariable is undefined but used injwt.verify(token, token_key)- The try-catch block executes even when no token exists
- Token verification should be performed only when a token is present
Consider refactoring to:
app.get("/", (req,res) => { + const token = req.cookies['login_email']; + if (!token) { + return res.status(200).sendFile(__dirname+'/pages/index.html'); + } try { const decoded = jwt.verify(token, token_key); const user_email = decoded.user_email; let found = false; userData.forEach((dt) => { if(dt.email == user_email) found = true; }) if(found) return res.status(200).sendFile(__dirname+'/pages/dashboard.html'); } catch (err) { console.log(err); - return res.status(500).json("error on server"); + // Token invalid/expired - clear it and show index page + res.clearCookie('login_email'); + return res.status(200).sendFile(__dirname+'/pages/index.html'); } return res.status(200).sendFile(__dirname+'/pages/index.html'); })
42-52: Improve environment separation instead of using "Test" suffixesThe renaming of routes with "Test" suffixes suggests a need for testing/staging environments. This approach can lead to confusion and maintenance issues.
Consider:
- Using environment variables to control routing behavior
- Implementing proper staging/production environment separation
- Using a configuration file to manage environment-specific routes
Example implementation:
// config.js const config = { production: { routes: { getIdea: '/getIdea', profile: '/profile', docs: '/docs' } }, staging: { routes: { getIdea: '/getIdeaTest', profile: '/profileTest', docs: '/docsTest' } } }; module.exports = config[process.env.NODE_ENV || 'production'];
Critical: Add essential security validations and utilize bcrypt for password hashing
The codebase has
bcryptas a dependency but it's not being utilized in the registration endpoint. The current implementation needs both validation and proper password hashing:+ const bcrypt = require('bcrypt'); app.post('/Testregister', async (req,res)=>{ const {name,email,password,checkpassword}=req.body; + // Input validation + if (!name?.trim() || !email?.trim() || !password || !checkpassword) { + return res.status(400).json("All fields are required"); + } + + // Email format validation + const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/; + if (!emailRegex.test(email)) { + return res.status(400).json("Invalid email format"); + } + + // Password matching + if (password !== checkpassword) { + return res.status(400).json("Passwords do not match"); + } + + // Password strength check + if (password.length < 8) { + return res.status(400).json("Password must be at least 8 characters"); + } let found=false; userData.forEach((dt)=>{ if(dt.email==email) found=true; }) if(found) { return res.status(400).json("a user exists with this email") } + // Hash password + const saltRounds = 10; + const hashedPassword = await bcrypt.hash(password, saltRounds); userData.push({ name: name.trim(), email: email.toLowerCase().trim(), - password, + password: hashedPassword, ideas:[] }) const token = jwt.sign( { user_email: email }, process.env.TOKEN_KEY ); return res.status(200).cookie('login_email',token).redirect('/'); })🔗 Analysis chain

210-240: Critical: Restore and enhance registration validationThe current implementation lacks essential validation and security measures:
- No password matching verification
- Missing input validation
- No password strength requirements
- No email format validation
- No input sanitization
Implement proper validation:
app.post('/Testregister',(req,res)=>{ const {name,email,password,checkpassword}=req.body; + // Input validation + if (!name || !email || !password || !checkpassword) { + return res.status(400).json("All fields are required"); + } + + // Email format validation + const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/; + if (!emailRegex.test(email)) { + return res.status(400).json("Invalid email format"); + } + + // Password matching + if (password !== checkpassword) { + return res.status(400).json("Passwords do not match"); + } + + // Password strength check + if (password.length < 8) { + return res.status(400).json("Password must be at least 8 characters"); + } let found=false; userData.forEach((dt)=>{ if(dt.email==email) found=true; }) if(found) { return res.status(400).json("a user exists with this email") } + // Sanitize inputs + const sanitizedName = name.trim(); + const sanitizedEmail = email.toLowerCase().trim(); userData.push({ - name, - email, + name: sanitizedName, + email: sanitizedEmail, password, ideas:[] }) const token = jwt.sign( { user_email: email }, process.env.TOKEN_KEY ); return res.status(200).cookie('login_email',token).redirect('/'); })Let's verify if there are any existing validation utilities in the codebase:

Line range hint 1-241: Critical: Address additional security concerns
Several security issues need attention:
- Passwords are stored in plain text
- No rate limiting on authentication endpoints
- No CSRF protection
- JWT token key potentially exposed
Recommended improvements:
- Implement password hashing using bcrypt
- Add rate limiting middleware (e.g., express-rate-limit)
- Implement CSRF protection (e.g., csurf middleware)
- Ensure JWT_SECRET is properly secured
- Add secure and httpOnly flags to cookies
Example implementation for some of these features:
const bcrypt = require('bcrypt');
const rateLimit = require('express-rate-limit');
const csrf = require('csurf');
// Rate limiting
const authLimiter = rateLimit({
windowMs: 15 * 60 * 1000, // 15 minutes
max: 5 // limit each IP to 5 requests per windowMs
});
app.use('/login', authLimiter);
app.use('/Testregister', authLimiter);
// CSRF protection
app.use(csrf({ cookie: true }));
// Secure cookies
app.use((req, res, next) => {
res.cookie('login_email', token, {
httpOnly: true,
secure: process.env.NODE_ENV === 'production',
sameSite: 'strict'
});
next();
});Let's check for existing security measures:
#!/bin/bash
# Search for security-related packages and implementations
rg -l "bcrypt|rate|limit|csrf|helmet" --type js1 participant
