[P0 Security] Mass Assignment Protection – $fillable für alle 18 Models (vibe-kanban 4a764a11)

Browse Source 
## Security Audit: Mass Assignment Protection

### Problem
Alle 18 Eloquent Models verwenden `protected $guarded = [];` – das bedeutet **kein Schutz** gegen Mass Assignment. Ein Angreifer könnte über manipulierte Requests sensible Felder wie `accepted`, `sats_paid`, `association_status`, `paid` oder `created_by` direkt setzen.

### Betroffene Dateien und empfohlene Änderungen

Ersetze in **jedem** der folgenden Models `protected $guarded = [];` durch ein explizites `protected $fillable = [...]` Array. Hier die Analyse pro Model:

**Höchstes Risiko (Finanzen & Identity):**

1. **`app/Models/PaymentEvent.php`** – Finanz-kritisch!
   - Sensible Felder (NICHT fillable): `einundzwanzig_pleb_id`, `year`, `amount`, `event_id`, `paid`, `btc_pay_invoice`
   - `$fillable` sollte leer oder minimal sein – alle Felder werden programmatisch gesetzt

2. **`app/Models/EinundzwanzigPleb.php`**
   - Sensible Felder: `association_status`, `application_for`, `nip05_handle`
   - `$fillable = ['npub', 'pubkey', 'email', 'no_email', 'application_text', 'archived_application_text']`

3. **`app/Models/Vote.php`**
   - Sensible Felder: `einundzwanzig_pleb_id`, `project_proposal_id`, `value`
   - `$fillable = ['reason']` – alle anderen Felder müssen programmatisch gesetzt werden

4. **`app/Models/ProjectProposal.php`**
   - Sensible Felder: `einundzwanzig_pleb_id`, `accepted`, `sats_paid`, `slug`
   - `$fillable = ['name', 'support_in_sats', 'description', 'website']`

5. **`app/Models/Election.php`**
   - Sensible Felder: `year`, `candidates`, `end_time`
   - `$fillable` sollte leer sein – nur Admin-gesteuert

**Mittleres Risiko (mit `created_by` auto-fill in boot):**

6. **`app/Models/Venue.php`** – `$fillable = ['name']` (slug & created_by auto-generiert)
7. **`app/Models/MeetupEvent.php`** – `$fillable = ['start']` (meetup_id, created_by, attendees guarded)
8. **`app/Models/CourseEvent.php`** – `$fillable = ['from', 'to']` (course_id, venue_id, created_by guarded)
9. **`app/Models/Course.php`** – `$fillable = ['name', 'description']` (lecturer_id, created_by guarded)
10. **`app/Models/Meetup.php`** – `$fillable = ['name']` (city_id, created_by, slug, github_data, simplified_geojson guarded)
11. **`app/Models/Lecturer.php`** – `$fillable = ['name']` (active, created_by, slug guarded)
12. **`app/Models/City.php`** – `$fillable = ['name']` (country_id, created_by, slug, osm_relation, simplified_geojson guarded)

**Niedrigeres Risiko (Lookup/Reference-Daten):**

13. **`app/Models/Event.php`** – `$fillable = []` (alle Felder: event_id, parent_event_id, pubkey, json, type sind extern gesteuert)
14. **`app/Models/RenderedEvent.php`** – `$fillable = []` (event_id, html, profile_image, profile_name alle system-generiert)
15. **`app/Models/Profile.php`** – `$fillable = ['name', 'display_name', 'picture', 'banner', 'website', 'about']` (pubkey, deleted, nip05, lud16, lud06 guarded)
16. **`app/Models/Category.php`** – `$fillable = ['name']`
17. **`app/Models/Country.php`** – `$fillable = ['name']` (code, language_codes guarded)
18. **`app/Models/Notification.php`** – `$fillable = ['name', 'description']` (einundzwanzig_pleb_id, category guarded)

### Vorgehen
1. Jedes Model öffnen und `$guarded = []` durch das oben definierte `$fillable` Array ersetzen
2. Prüfen, ob bestehende `::create()` oder `::update()` Aufrufe noch funktionieren – ggf. müssen explizite Feld-Zuweisungen ergänzt werden
3. Für jedes geänderte Model einen Pest-Test schreiben, der verifiziert, dass Mass Assignment von sensiblen Feldern blockiert wird
4. `vendor/bin/pint --dirty` ausführen
5. Bestehende Tests laufen lassen: `php artisan test --compact`

### Akzeptanzkriterien
- Kein Model hat mehr `$guarded = []`
- Alle sensiblen Felder (status, paid, accepted, created_by, slug, IDs) sind NICHT in `$fillable`
- Bestehende Features funktionieren weiterhin (Tests grün)
- Neue Tests verifizieren Mass Assignment Protection
