Security Review for your FastAPI project
Expert security review for FastAPI applications. We find and fix FastAPI-specific security issues that affect production apps. From $19.
FastAPI security review issues we find
Common security review problems specific to FastAPI applications.
Missing authentication on endpoints
API routes that handle sensitive data or actions without any auth middleware — Depends() for authentication is simply not included in the route definition.
No CORS configuration
CORSMiddleware either missing (blocking all cross-origin requests) or set to allow_origins=['*'] (allowing any website to call your API).
Missing error handling middleware
Unhandled exceptions return raw 500 errors with stack traces to clients, leaking internal code structure and potentially sensitive information.
What our FastAPI security review covers
Authentication & authorization
Login flows, session management, role-based access, token handling, and OAuth integrations.
API security
Input validation, rate limiting, CORS configuration, and protection against injection attacks.
Data exposure
Secrets in source code, environment variable handling, database access controls, and sensitive data in client bundles.
Infrastructure configuration
HTTPS enforcement, security headers, cookie flags, CSP policies, and server hardening.
Dependency vulnerabilities
Known CVEs in your npm/pip packages, outdated libraries, and supply chain risks.
Database security
Row-level security policies, query injection prevention, backup configuration, and access controls.
