A reviewer found a hardcoded OpenAI API key inside a mobile app bundle, which anyone can extract and abuse. Keep provider keys on the server, expose a backend proxy that authenticates the client, enforces quotas/rate limits, and calls OpenAI on behalf of the app.
Leaked keys lead to billing abuse, data exposure, and incident response overhead.
Backend teams must provide a safe access pattern for AI providers across mobile and web clients.
-
terminal
Scan source and built artifacts for secrets and add CI/CD gates to block merges when secrets are detected.
-
terminal
E2E test the proxy flow: client auth -> backend token validation and rate limits -> server-side OpenAI call with per-user attribution and logging.
Legacy codebase integration strategies...
- 01.
Insert a backend-for-frontend proxy in front of AI providers, rotate compromised keys, and deprecate direct client calls.
- 02.
Gate older app versions by feature flags or server checks and add WAF rules to block direct provider traffic from clients.
Fresh architecture paradigms...
- 01.
Adopt a backend-for-frontend pattern from day one with short-lived client tokens and server-held provider keys.
- 02.
Build in per-user quotas, request logging, and cost attribution before enabling any client-facing AI features.
