Webhook Signature Verification Scanner
Find webhook handlers that appear to trust provider events without verifying signatures.
How this scan works
- Requires the same repo access as the Source Code SAST scanner — shares the file scan
- Locates likely webhook routes (/api/webhooks/*, files importing Stripe/GitHub/Creem SDKs)
- Flags handlers with no signature-header check (stripe-signature, x-hub-signature-256, HMAC compare) before processing the payload
