Vibe coding security: where fast-built apps leak

  1. 1.

    API keys and refresh tokens committed to the repository

  2. 2.

    Buyer PII stored unencrypted, kept indefinitely, readable by everyone

  3. 3.

    No access logs, so an incident cannot be reconstructed

  4. 4.

    Authorization checked in the frontend and skipped by the API

Buyer data enters from a marketplace API (here Amazon's, through a restricted data token) into an app inside a protected boundary with a secrets vault, encrypted store, access log and an anonymizer in front of third-party AI APIs; a security review checks code and controls.RESTRICTED DATA BOUNDARYRDTkeysencryptno PIIverifyMARKETPLACE APIorders / buyer dataYOUR APPAI-built or legacySECRETS VAULTAPI credentialsENCRYPTED STOREPII, time-limitedACCESS LOGevery readANONYMIZERstrips PIIAI APIthird partySECURITY REVIEWcode + controls

Questions engineers ask us.

Q01Is this a penetration test?

No. We review code, configuration and data handling. We do not sell penetration tests or certifications.

Q02What is Amazon's Data Protection Policy?

Amazon's rules for developers handling SP-API data, above all buyer PII: encryption, access control, logging, retention and incident response.

Q03Can you review an app built entirely with AI tools?

Yes. That is where vibe coding security matters most: the app works, but access control, secrets and data retention were never designed.

Q04Does a review make us compliant?

It closes gaps and documents the controls. Decisions on PII access and audits stay with Amazon; nobody can guarantee them.
