OWASP API Security Top 10 Vulnerabilities We Detect

AI Agents Built for API Security

Our agents are trained on the OWASP API Security Top 10 (2023). They understand the nuances of REST API security that traditional web scanners miss.

Broken Object Level Authorization

API1:2023
critical

APIs expose endpoints that handle object identifiers, creating opportunities for attackers to access other users' data by manipulating IDs in requests.

// Vulnerable: No ownership check GET /api/orders/12345 // Returns order data regardless of who owns it
// Fixed: Verify ownership app.get('/api/orders/:id', async (req, res) => { const order = await db.orders.findById(req.params.id); if (order.userId !== req.user.id) { return res.status(403).json({ error: 'Forbidden' }); } res.json(order); });

Broken Authentication

API2:2023
critical

Weak authentication mechanisms allow attackers to compromise tokens, exploit implementation flaws, or bypass authentication entirely.

// Vulnerable: Weak token validation const token = req.headers.authorization; if (token) { req.user = jwt.decode(token); // Not verified! }
// Fixed: Proper JWT verification const token = req.headers.authorization?.split(' ')[1]; try { req.user = jwt.verify(token, process.env.JWT_SECRET); } catch (err) { return res.status(401).json({ error: 'Unauthorized' }); }

Broken Object Property Level Authorization

API3:2023
high

APIs allow users to access or modify object properties they shouldn't. Includes excessive data exposure and mass assignment vulnerabilities.

// Vulnerable: Mass assignment app.put('/api/users/:id', async (req, res) => { await db.users.update(req.params.id, req.body); // User can set isAdmin: true! });
// Fixed: Whitelist allowed fields const allowedFields = ['name', 'email', 'avatar']; const updates = pick(req.body, allowedFields); await db.users.update(req.params.id, updates);

Unrestricted Resource Consumption

API4:2023
high

APIs don't limit resource consumption, allowing attackers to exhaust system resources through excessive requests, large payloads, or expensive operations.

// Vulnerable: No rate limiting app.post('/api/search', async (req, res) => { const results = await db.search(req.body.query); res.json(results); // Can be called unlimited times });
// Fixed: Rate limiting + pagination import rateLimit from 'express-rate-limit'; const limiter = rateLimit({ windowMs: 60000, max: 100 }); app.post('/api/search', limiter, async (req, res) => { const { query, page = 1, limit = 20 } = req.body; const results = await db.search(query, { page, limit }); res.json(results); });
