# CodeQL Query: Sensitive Data to HTTP Response
|
|
|
|
## Ziel
|
|
Finde Fluesse sensibler Daten in HTTP-/API-Responses oder Exception-Bodies.
|
|
|
|
## Sources
|
|
- Sensible Payment-Felder: pan, cvv, track2, cardNumber, pin, expiry
|
|
- Interne Payment DTOs mit sensitiven Attributen
|
|
|
|
## Sinks
|
|
- JSON serializer / response builder
|
|
- Exception payload / error handler response
|
|
- Template rendering output
|
|
|
|
## Mapped Controls
|
|
- `API-009`: API-Antworten minimieren sensible Daten
|
|
- `API-015`: Interne Fehler ohne sensitive Daten an Client
|
|
- `ERROR-005`: Ausnahmebehandlung gibt keine sensitiven Rohdaten zurueck
|
|
- `REPORT-006`: Reports offenbaren nur rollenerforderliche Daten
