Why Node.js Apps Get Hacked
Node.js backends power most modern startups, and their security comes down to how carefully you handle input, dependencies, and outbound requests. The npm dependency tree is enormous, prototype-pollution and known-CVE packages slip in constantly, and server-side fetch patterns invite SSRF. We scan the exposed surface of your Node service.
Common Node.js Vulnerabilities
Vulnerable npm dependencies
Deep dependency trees accumulate known CVEs fast. Outdated or abandoned packages are a leading cause of server compromise via supply chain.
Injection (SQL / NoSQL / command)
Unparameterized queries and shelling out with user input lead to SQL/NoSQL injection and command injection — full data or server takeover.
SSRF via server-side fetch
Fetching attacker-controlled URLs server-side can reach internal services and cloud metadata endpoints (169.254.169.254) to steal credentials.
Prototype pollution
Merging untrusted JSON into objects without guarding __proto__ can corrupt application behavior and escalate to RCE in some libraries.
Verbose errors & missing headers
Stack traces in responses leak internal structure; missing rate limits and security headers expose the API to abuse.
What the Sable Scan Checks
Exposed secrets & API keys
We scan your client-side bundles and responses for leaked API keys, tokens, database URLs, and 100+ secret patterns that ship to the browser by accident.
Security headers & TLS
HSTS, CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy, and TLS protocol/cipher configuration — graded A-F with copy-paste fixes.
CORS & access control
Overly permissive CORS, wildcard origins with credentials, and broken object-level authorization (IDOR/BOLA) where one user can reach another user's data.
Injection & API surface
SQL/NoSQL injection, exposed OpenAPI/Swagger specs, GraphQL introspection, mass assignment, missing rate limits, and excessive data exposure.
OWASP Top 10 coverage
Autonomous pentesting agents test against the full OWASP Top 10 2025, validate each finding with a proof-of-concept, and re-test after you fix.
Validated findings, not noise
Every reported issue is confirmed by an agent before it reaches you — so you get real, exploitable findings with severity and remediation, not scanner spam.
