# CodeQL Query: Tenant Context Loss
|
|
|
|
## Ziel
|
|
Finde Datenbank-, Cache- oder Exportpfade ohne durchgehenden Tenant-Kontext.
|
|
|
|
## Sources
|
|
- Request tenant (header, token, session)
|
|
- Device tenant
|
|
- User tenant
|
|
|
|
## Danger Patterns
|
|
- DB Query ohne tenant filter / WHERE clause
|
|
- Cache key ohne tenant prefix
|
|
- Export job ohne tenant binding
|
|
- Report query ohne Mandanteneinschraenkung
|
|
|
|
## Mapped Controls
|
|
- `TENANT-001`: Mandantenkontext serverseitig validiert
|
|
- `TENANT-002`: Datenabfragen mandantenbeschraenkt
|
|
- `TENANT-006`: Caching beruecksichtigt Mandantenkontext
|
|
- `TENANT-008`: Datenexporte erzwingen Mandantenisolation
