Security Issues in Augment Code Code

Augment inherits the security posture of your existing codebase — if you have insecure patterns in the code it learns from, it will replicate them. Generated code may use deprecated internal APIs that had known security issues. It may also bypass existing validation middleware if it doesn't recognize why that middleware exists

Review all Augment-generated code for security-sensitive operations: authentication, authorization, data access, and external calls. Ensure generated code goes through the same security review process as hand-written code. Add security linting rules that apply to all code regardless of authorship. Document security-critical patterns so Augment (and developers) understand why they exist

Every Augment Code app needs authentication — verifying who the user is — and authorization — verifying what they're allowed to do. Check that every API route and server action verifies the user's identity before processing requests. Check that users can only access their own data. A common Augment Code pattern is adding auth to the UI but not the API, which means anyone with the endpoint URL can access data directly.

Never trust data coming from the client. Every form submission, URL parameter, and API request body should be validated server-side before processing. Use a schema validation library like Zod to define expected shapes and reject anything that doesn't match. This prevents injection attacks, data corruption, and unexpected crashes.

Configure security headers to protect against common web attacks: Content-Security-Policy to prevent XSS, Strict-Transport-Security to enforce HTTPS, X-Frame-Options to prevent clickjacking, and X-Content-Type-Options to prevent MIME sniffing. Most hosting platforms let you configure these in a headers file or configuration.

If your app handles user data, processes payments, or stores sensitive information, a professional security review is essential before launch. Our security scan ($19) checks for the most critical vulnerabilities, and our full security review service provides a comprehensive assessment with remediation guidance.
