THE THREAT

Your APIs Are Your
Biggest Attack Surface

APIs are no longer behind the scenes — they are the product. Every endpoint you expose is a door. In 2025, APIs accounted for 17% of all published vulnerabilities. Attackers aren't scanning ports anymore — they're reading your API docs.

Anatomy of a SaaS API Attack (2026)

API Recon Docs, Swagger, exposed schemas Auth Bypass Broken JWT, missing checks BOLA / IDOR Enumerate IDs, access other users Data Harvest Mass scrape PII, export via API Breach NDB + Fines Attacker finds public API docs or /swagger Weak token, no rate limit, broken session Change user_id in request = other's data Automated scraping of all user records Privacy Act notification Often automated — full data exfiltration in hours, not weeks

Software & SaaS: The Top Targets

Wallarm's 2026 analysis of 60 API breaches found Software (15%), AI platforms (15%), cybersecurity vendors (13%), and SaaS (8%) are the most-targeted sectors. The pattern is clear: if your product has APIs, you're in the crosshairs. Real-world examples include Postman workspaces leaking 30,000 production secrets, and Spoutible's API exposing bcrypt password hashes via simple ID enumeration.

OWASP API SECURITY TOP 10

The 5 API Vulnerabilities
That Cause Most Breaches

Based on OWASP's 2023 API Security Top 10 and mapped to real-world incidents from 2024–2026. These five alone account for the vast majority of API-related data breaches.

1

Broken Object Level Authorisation (BOLA)

API1:2023 — 40% of all API attacks

The attacker changes an object ID in the request (user_id, order_id, file_id) and gets another user's data. This is the #1 API vulnerability because most frameworks don't enforce object-level permissions by default — developers have to implement it manually on every single endpoint.

Real-world: Spoutible's API let attackers increment user IDs to harvest account data including bcrypt password hashes. The API checked if you were logged in — but not whose data you were requesting.
2

Broken Authentication

API2:2023 — 52% of incidents (Wallarm)

Weak JWTs, missing token expiry, predictable API keys, or authentication that's only enforced on some endpoints. In 2025, "Missing Authentication" was the single most frequent API vulnerability at 17% of all incidents. Many SaaS apps protect the frontend but leave internal/admin APIs wide open.

Real-world: Cisco ISE allowed unauthenticated attackers to execute code with a single crafted API request. No credentials needed — the endpoint simply had no auth check.
3

Broken Object Property Level Auth

API3:2023 — Excessive Data Exposure + Mass Assignment

Your API returns more data than the frontend needs (exposing internal fields, tokens, PII), or accepts fields it shouldn't (letting users set their own role or permissions). This merged two former OWASP entries because the root cause is the same: the API trusts whatever comes in and sends everything back out.

Real-world: Intel India's partner portal APIs returned entire JSON objects including plaintext credentials — Salesforce CRM passwords, payment processor tokens, and session keys for backend services — none of which the frontend ever displayed.
4

Unrestricted Resource Consumption

API4:2023 — No Rate Limits = Unlimited Abuse

Without rate limiting, attackers can brute-force credentials, enumerate users, scrape your entire database, or run up your cloud bill. This replaced "Lack of Resources and Rate Limiting" in the 2023 update because the impact goes beyond availability — it enables data theft at scale.

Pattern: Attacker writes a script that calls /api/users/{id} for IDs 1 through 10,000,000. Without rate limits, they dump your entire user table in hours. Your cloud bill spikes. Your users get breached.
5

Broken Function Level Authorisation (BFLA)

API5:2023 — Privilege Escalation via API

A regular user can access admin endpoints by guessing or discovering them. Often the frontend hides admin buttons — but the API endpoints still exist and respond to any authenticated user. This is especially dangerous in SaaS with tiered pricing: free users accessing premium API features, or users escalating to admin.

Pattern: Frontend only shows the "Delete User" button to admins. But DELETE /api/admin/users/123 works for any authenticated user because authorisation only exists in the UI, not the API.

New in OWASP API Top 10 2023

Three risks were added: Unrestricted Access to Sensitive Business Flows (API6 — automated abuse of legitimate functions like ticket scalping or credential stuffing), Server-Side Request Forgery (API7 — SSRF via API parameters), and Unsafe Consumption of APIs (API10 — trusting data from third-party APIs without validation). The last one is critical for SaaS: if your app integrates with Stripe, Twilio, or any external API, you need to validate their responses too.

WEB APPLICATION SECURITY

SaaS Web App Attack Vectors
Beyond the API Layer

APIs aren't your only surface. Your web frontend, authentication flows, client-side code, and deployment infrastructure are all targets. Here's what attackers look for in SaaS applications.

🎯

Client-Side & Session Attacks

Your frontend is an attacker's playground
!
Critical

Cross-Site Scripting (XSS) in SaaS

Cross-site issues became the #1 API weakness by attack volume in 2025. In SaaS, XSS is especially dangerous because your app handles multi-tenant data. A stored XSS in a shared workspace feature (comments, file names, custom fields) can steal session tokens from every user who views that content — across different tenant accounts.

!
High

Authentication Flow Attacks

OAuth misconfiguration, weak session management, and insecure password reset flows. Common SaaS patterns: open redirect after login (used for phishing), JWT with "none" algorithm accepted, refresh tokens that never expire, password reset tokens sent in URL query strings. If you offer SSO, your SAML/OIDC implementation is an attack surface.

!
High

Tenant Isolation Failures

The #1 SaaS-specific risk. If your multi-tenancy relies on application-level filtering (WHERE tenant_id = X) rather than infrastructure isolation, a single bug can expose every customer's data. This includes: shared database queries missing tenant filters, cached responses served to wrong tenants, file storage paths without tenant scoping, and background jobs processing cross-tenant data.

🏗️

Infrastructure & Supply Chain

Your deployment is part of your attack surface
!
High

Server-Side Request Forgery (SSRF)

If your SaaS lets users provide URLs (webhooks, import from URL, profile picture from URL), attackers can make your server request internal resources — cloud metadata endpoints, internal services, admin panels. In AWS, http://169.254.169.254 returns instance credentials. SSRF is now in the OWASP API Top 10 because API-driven architectures expose more URL-accepting endpoints.

!
Medium

Dependency & Supply Chain Risks

Supply-chain breaches accounted for 20% of all incidents in 2025. Your SaaS depends on hundreds of npm/pip packages, third-party APIs, and cloud services. Each one is a potential entry point. The Postman workspace breach exposed 30,000 production secrets because developers saved API keys in public workspaces without realising they were accessible.

THE HARDENING PLAYBOOK

10 Controls Every SaaS
Must Implement

Prioritised by impact. Controls 1–4 address the vulnerabilities behind the majority of SaaS breaches. Based on OWASP guidelines, real-world incident data, and what we find during penetration tests.

🔐

Authentication & Authorisation

Controls 1–4 • Highest Impact
1
Critical

Enforce Object-Level Authorisation on Every Endpoint

Don't rely on framework-level auth alone. Every API endpoint that accesses a resource must verify that the authenticated user owns or has permission to access that specific object. Centralise this in middleware or a policy engine — don't trust individual developers to add checks on every route. This single control prevents BOLA, the #1 API vulnerability.

Pattern: middleware.authorize(req.user, resource.owner_id)

2
Critical

Implement Proper JWT/Session Management

Short-lived access tokens (15 min), secure refresh token rotation, proper audience and issuer validation, and never use "none" algorithm. Store tokens in httpOnly secure cookies, not localStorage. Implement token revocation for logout and password changes. 52% of API breaches involve broken authentication — this is where most SaaS products fail.

Tools: Auth0, Clerk, Supabase Auth, or custom with jose/jsonwebtoken

3
Critical

Rate Limit Everything

Apply rate limits at multiple layers: per-user, per-IP, per-endpoint, and globally. Authentication endpoints need aggressive limits (5 attempts/min). Public APIs need quota enforcement. Without rate limiting, BOLA becomes mass data exfiltration, brute-force becomes trivial, and your cloud bill becomes a weapon (denial-of-wallet).

Tools: express-rate-limit, Kong, AWS WAF, Cloudflare Rate Limiting

4
High

Enforce Tenant Isolation at the Data Layer

Never rely solely on application-level WHERE clauses for multi-tenancy. Use Row-Level Security (RLS) in PostgreSQL, separate schemas per tenant, or dedicated databases for high-value customers. Every database query, cache key, file path, and background job must be tenant-scoped. Test this: can Tenant A's admin ever see Tenant B's data?

Pattern: PostgreSQL RLS + tenant_id enforced at connection level

🛡️

API Hygiene & Defence in Depth

Controls 5–7 • Reduce Your Surface
5
High

Validate Input, Sanitise Output — Everywhere

Use schema validation (Zod, Joi, Pydantic) on every API input. Reject unexpected fields. Encode all output to prevent XSS. Parameterise all database queries — no string concatenation. Validate file uploads by content, not just extension. With cross-site issues now the #1 API attack by volume, input/output hygiene is non-negotiable.

Pattern: Zod schema per endpoint + DOMPurify for user-generated HTML

6
High

Minimise API Response Data

Only return the fields the client needs. Never expose internal IDs, server paths, stack traces, or metadata. Use separate response DTOs — don't serialise your database models directly. The Intel breach happened because APIs returned full JSON objects with fields the frontend never used, including plaintext credentials for other services.

Pattern: ResponseDTO layer between database models and API responses

7
Medium

Secure Your API Documentation

Don't expose Swagger UI, OpenAPI specs, or GraphQL introspection in production. If you must have public API docs, ensure they don't reveal internal endpoints, admin routes, or deprecated endpoints that still work. Attackers use your API docs as a roadmap — every endpoint documented is an endpoint tested.

Check: /swagger, /api-docs, /graphql (with introspection query)

📊

Monitoring & Response

Controls 8–10 • Detect and Respond
8
High

Log Every API Action with Context

Log who (user_id, tenant_id, IP), what (endpoint, method, params), when (timestamp), and outcome (status, error). Structured logging (JSON) with correlation IDs. Store logs for at least 180 days. Without logs, you can't investigate breaches, prove NZ Privacy Act compliance, or support cyber insurance claims.

Tools: Datadog, Sentry, AWS CloudWatch, ELK Stack

9
Medium

Implement API Anomaly Detection

Alert on unusual patterns: sudden spikes in requests, sequential ID enumeration, requests from unexpected geolocations, or a user accessing far more resources than normal. Most SaaS breaches involve automated scraping that's trivially detectable — if you're watching. The average breach takes 277 days to detect without monitoring.

Tools: AWS GuardDuty, Cloudflare Bot Management, custom alerts

10
Recommended

Dependency Scanning & Secrets Management

Run Dependabot/Snyk on every PR. Never hardcode API keys, database credentials, or secrets in code. Use a secrets manager (AWS Secrets Manager, Vault, Doppler). Rotate keys regularly. Scan git history for accidentally committed secrets — the Postman breach exposed 30,000 production secrets sitting in public workspaces.

Tools: GitHub Advanced Security, Snyk, TruffleHog, GitLeaks

SELF-ASSESSMENT

The SaaS API & Web
Security Audit

Print this page and work through each item. If you can't tick more than half, your SaaS product needs a professional security assessment before an attacker finds what you've missed.

Object-level authorisation on every endpoint
Test: Can User A's token access User B's resources by changing the ID?
No endpoint missing authentication
Test: Hit every endpoint with no auth header — does anything respond with data?
JWT/tokens have short expiry + rotation
Access tokens ≤15 min, refresh tokens rotate on use, revoked on logout
Rate limiting on all endpoints
Auth endpoints: ≤5/min. Public API: quota enforced. No unlimited scraping possible
Tenant isolation verified at data layer
RLS enabled, or tenant_id enforced at DB/ORM level — not just application code
Input validation on every API endpoint
Schema validation (Zod/Joi/Pydantic), parameterised queries, no raw SQL
API responses don't leak internal data
No internal IDs, stack traces, DB schemas, or unused fields in responses
No Swagger/API docs exposed in production
Check: /swagger, /api-docs, /graphql?query={__schema{types{name}}}
Security headers configured
CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy
No secrets in code or git history
Run: trufflehog git file://. --only-verified — zero results expected
Dependency vulnerabilities patched
Dependabot/Snyk enabled, no critical CVEs in production dependencies
API actions logged with full context
Who, what, when, outcome — structured JSON, retained ≥180 days

💡 Scoring Your Audit

10–12 ticks: Solid foundation — regular pen testing will catch the edge cases.
6–9 ticks: Significant gaps — you're exposed to the most common attack patterns.
0–5 ticks: Critical risk — an automated scanner would find issues. A manual pen test would find far more.

SHOW ME THE CODE

Vulnerable vs Secure:
API Code Patterns

These are the exact patterns we find during SaaS penetration tests. Copy-paste the secure versions into your codebase. Each example maps to an OWASP API risk and shows the fix in under 10 lines.

❌ BOLA — Broken Object Level Authorisation (API1)

// VULNERABLE: No ownership check — any user can access any order app.get('/api/orders/:id', auth, async (req, res) => { const order = await Order.findById(req.params.id); res.json(order); // ← Attacker changes :id, gets other users' orders });

✅ SECURE: Ownership enforced at query level

app.get('/api/orders/:id', auth, async (req, res) => { const order = await Order.findOne({ _id: req.params.id, tenant_id: req.user.tenant_id, // ← Scoped to tenant user_id: req.user.id // ← Scoped to user }); if (!order) return res.status(404).json({ error: 'Not found' }); res.json(order); });

❌ BROKEN AUTH — JWT Without Validation (API2)

// VULNERABLE: Accepts any algorithm, no expiry check, secrets in code const decoded = jwt.verify(token, 'mysecret123'); // ← Hardcoded secret // No audience check, no issuer check, accepts "alg": "none" req.user = decoded;

✅ SECURE: Strict JWT validation

const decoded = jwt.verify(token, process.env.JWT_SECRET, { algorithms: ['RS256'], // ← Only allow RS256 audience: 'https://api.yourapp.com', issuer: 'https://auth.yourapp.com', maxAge: '15m', // ← 15-min expiry clockTolerance: 30, });

❌ EXCESSIVE DATA EXPOSURE (API3)

// VULNERABLE: Returns entire database model including internal fields app.get('/api/users/:id', auth, async (req, res) => { const user = await User.findById(req.params.id); res.json(user); // ← Exposes password_hash, internal_notes, stripe_id, role });

✅ SECURE: Response DTO with explicit field selection

const UserResponseDTO = (user) => ({ id: user.id, name: user.name, email: user.email, avatar_url: user.avatar_url, created_at: user.created_at, // Explicitly omit: password_hash, stripe_id, internal_notes, role }); app.get('/api/users/:id', auth, authorizeOwner, async (req, res) => { const user = await User.findById(req.params.id); res.json(UserResponseDTO(user)); // ← Only safe fields });

❌ NO RATE LIMITING — Unlimited Enumeration (API4)

// VULNERABLE: No rate limit on login — brute-force trivial app.post('/api/auth/login', async (req, res) => { const user = await User.findOne({ email: req.body.email }); if (!user || !bcrypt.compareSync(req.body.password, user.hash)) return res.status(401).json({ error: 'Invalid email' }); // ← Leaks valid emails // No rate limit, no account lockout, no CAPTCHA res.json({ token: generateToken(user) }); });

✅ SECURE: Rate limited + generic error + lockout

const loginLimiter = rateLimit({ windowMs: 15 * 60 * 1000, // 15 minutes max: 5, // 5 attempts per window keyGenerator: (req) => req.body.email || req.ip, }); app.post('/api/auth/login', loginLimiter, async (req, res) => { const user = await User.findOne({ email: req.body.email }); if (!user || !await bcrypt.compare(req.body.password, user.hash)) return res.status(401).json({ error: 'Invalid credentials' }); // ↑ Generic — no email enumeration res.json({ token: generateToken(user) }); });

❌ TENANT ISOLATION FAILURE — SaaS-Specific

// VULNERABLE: Tenant filter only in application code — easily missed app.get('/api/invoices', auth, async (req, res) => { const invoices = await db.query( 'SELECT * FROM invoices WHERE tenant_id = $1', [req.user.tenant_id] ); // ← Works here, but what about the 200 other queries? res.json(invoices); });

✅ SECURE: Row-Level Security enforced at database level

-- PostgreSQL RLS: enforced on EVERY query, regardless of app code ALTER TABLE invoices ENABLE ROW LEVEL SECURITY; CREATE POLICY tenant_isolation ON invoices USING (tenant_id = current_setting('app.tenant_id')::uuid); -- Set tenant context at connection level (middleware) await db.query(`SET app.tenant_id = '${req.user.tenant_id}'`); // Now ALL queries are automatically scoped — even JOINs, subqueries

NZ COMPLIANCE

Privacy Act 2020 &
API Security for NZ SaaS

If your SaaS handles personal information of New Zealanders, the Privacy Act 2020 applies — regardless of where your company is based. API vulnerabilities don't just cause breaches; they trigger mandatory legal obligations.

Information Privacy
Principles (IPPs)
Privacy Act 2020

Mandatory Breach Notification (Part 6A)

If a privacy breach has caused, or is likely to cause, serious harm to affected individuals, you must notify the Privacy Commissioner and affected individuals "as soon as practicable." For SaaS companies, API breaches that expose customer PII — names, emails, billing data, usage data — almost always meet this threshold. Failure to notify is an interference with privacy and can result in investigation, compliance orders, and reputational damage.

5

IPP 5 — Security Safeguards

Agencies must protect personal information "by such security safeguards as it is reasonable in the circumstances to take" against loss, unauthorised access, use, modification, or disclosure. For SaaS, this means: proper API authentication and authorisation, encryption in transit and at rest, access controls, logging, and regular security testing. A BOLA vulnerability exposing customer data would likely be considered a failure of "reasonable safeguards."

11

IPP 11 — Limits on Disclosure

Personal information can only be disclosed for the purpose it was collected. An API that over-returns data (Excessive Data Exposure, OWASP API3) technically discloses information beyond its intended purpose. If your API returns a user's full profile (including internal fields) when the request only needed their name, that's an IPP 11 issue — even without an attacker exploiting it.

SaaS Scenario OWASP Risk Privacy Act Impact
User A accesses User B's data via BOLA API1 — BOLA Notifiable breach (Part 6A)
API returns internal fields with PII API3 — Property Auth IPP 5 + IPP 11 violation
No rate limit enables mass scraping API4 — Resource Notifiable if PII exposed
Unauthenticated endpoint leaks data API2 — Auth IPP 5 failure + notification
Third-party API integration leaks data API10 — Unsafe IPP 5 + IPP 11 (disclosure)

💡 For NZ Startups Targeting Overseas Markets

If you handle data from EU residents, GDPR applies (fines up to 4% of global revenue). If you handle US health data, HIPAA applies. If you're SOC 2 certified (increasingly required by enterprise customers), API security testing is a core control. Getting your API security right isn't just about protecting data — it's about winning enterprise deals and entering regulated markets.

SAMPLE FINDINGS

What We Actually Find
in SaaS Pen Tests

These are anonymised examples from real WeHack engagements. Every SaaS product we've tested has had at least one critical finding. Here's what they look like.

C

BOLA: Any User Can Download Any Invoice PDF

Critical • B2B SaaS Platform • Found in 2 hours

GET /api/invoices/INV-4521/pdf returned the PDF for invoice 4521 regardless of which user made the request. By incrementing the invoice number, an attacker could download every customer invoice in the system — including billing amounts, company names, and contact details.

Fix applied: Added WHERE tenant_id = req.user.tenant_id ownership check. Switched invoice IDs from sequential numbers to UUIDs to prevent enumeration.
C

Auth Bypass: Admin API Accessible to Free Users

Critical • Project Management SaaS • Found in 30 minutes

The /api/admin/users endpoint checked for a valid JWT but didn't verify the user's role. Any authenticated user — including free-tier accounts — could list all users, change permissions, and delete accounts across the entire platform.

Fix applied: Added role-based middleware (requireRole('admin')) to all /api/admin/* routes. Moved admin endpoints behind a separate subdomain with stricter auth.
H

Data Exposure: API Returns Stripe Customer IDs

High • E-commerce SaaS • Found in 1 hour

The user profile endpoint returned the raw database model, which included stripe_customer_id, internal_notes, and password_reset_token. The Stripe ID alone could be used to look up payment methods via Stripe's API if combined with a leaked Stripe key.

Fix applied: Implemented Response DTO layer — only id, name, email, and avatar_url returned. Added automated tests that fail if response contains unexpected fields.
M

Tenant Bleed: Cached Dashboard Served to Wrong User

Medium • Analytics SaaS • Found in 3 hours

Dashboard data was cached by endpoint URL but not by tenant. When Tenant A loaded /api/dashboard/overview, the response was cached. Tenant B requesting the same URL received Tenant A's analytics data — revenue figures, customer counts, and usage metrics.

Fix applied: Added tenant_id to all cache keys. Implemented cache-busting middleware that includes tenant context. Added automated cross-tenant tests to CI pipeline.
