Security Review — Secret Leakage Auditor

To audit a TypeScript package for secret leakage, you trace environment variable prefixes, error messages, and generated schemas to inventory all leakage points. This validates that only approved public keys are exposed.

Environment variables leak into TypeScript build outputs through misconfigured public config, generated schemas, and error messages. Leakage happens when env var prefixes bypass allowlists and secrets are included in client bundles.

You check error messages for sensitive config data by validating them against an approved public key allowlist. This ensures error responses and generated schemas do not reveal environment variables or secrets to clients.

Yes, the secret leakage audit works with any TypeScript config setup by tracing environment variable prefixes, build artifacts, and endpoints to enforce allowlists. It validates that only approved public keys are exposed regardless of the specific configuration.

The best way to prevent secrets from reaching public config endpoints is to enforce allowlists and validate endpoint runtime behavior with guardrails. This ensures only approved public config keys are exposed while tracing all inventory to block secret leakage.

You should use an automated secrets audit for TypeScript packages when you need to secure software supply chains during development and deployment. It provides remediation guidance and guardrails to prevent leakage through misconfigured endpoints and build outputs.
