# CodeQL Query: Cache and Export Leak
|
|
|
|
## Ziel
|
|
Finde Leaks sensibler Daten in Caches, Files, Reports und Exportpfaden.
|
|
|
|
## Sources
|
|
- Sensitive payment attributes (pan, cvv, track2)
|
|
- Full transaction objects with sensitive fields
|
|
|
|
## Sinks
|
|
- Redis/Memcache writes
|
|
- Temp file writes
|
|
- CSV/PDF/Excel exports
|
|
- Report builders
|
|
|
|
## Mapped Controls
|
|
- `DATA-004`: Temporaere Speicher ohne sensitive Daten
|
|
- `DATA-005`: Sensitive Daten in Telemetrie nicht offengelegt
|
|
- `DATA-011`: Batch/Queue ohne unnoetige sensitive Felder
|
|
- `REPORT-005`: Berichte beruecksichtigen Zeitzonen konsistent
