+# invoiceninja-0004 — CWE-407 Settings Saver O(C×S) in_array inside casts loop
+
+**MOAD:** 0001 (CWE-407 Sedimentary Defect)
+**Severity:** MEDIUM
+**Ratio:** ~6x at C=261 / S=6 — validated in benchmark
+
+## Location
+
+- `app/Utils/Traits/SettingsSaver.php` — `validateSettings()` lines 53, 66
+- `app/Utils/Traits/CompanySettingsSaver.php` — `validateSettings()` lines 124, 138; `checkSettingType()` lines 186, 207
+- `app/Utils/Traits/ClientGroupSettingsSaver.php` — `validateSettings()` line 110
+
+## Pattern
+
+All three traits iterate `foreach ($casts as $key => $value)` where `$casts = CompanySettings::$casts`
+contains **261 entries**. Inside the loop each iteration calls:
+
+```php
+in_array($key, CompanySettings::$string_casts)  // O(6) scan × 261 iterations = O(1566)
+in_array($key, $this->string_ids)               // O(6) scan × 261 iterations = O(1566)
+```
+
+Both lists are small (6 entries each) but fixed-size arrays scanned linearly per cast key.
+Called on every company/client/group settings save request.
+
+## Fix
+
+Hoist both arrays to hash sets with `array_flip()` before the loop, then replace
+`in_array($key, $list)` with `isset($hash[$key])` — O(1) per lookup.
+
+```php
+$string_casts_set = array_flip(CompanySettings::$string_casts);
+$string_ids_set   = array_flip($this->string_ids);
+// ...inside loop:
+if (isset($string_casts_set[$key])) { ... }
+if (isset($string_ids_set[$key])) { ... }
+```
+
+## Speedup
+
+~6x op-count reduction at C=261, S=6 (measured in benchmark).
+
+## Affected Routes
+
+Every settings save: `PUT /api/v1/companies/{id}`, `PUT /api/v1/clients/{id}`, group settings.

+# invoiceninja-0005 — CWE-312 CBAPowerBoard CreditCard vault_token logged verbatim
+
+**MOAD:** 0004 (Logged Secret)
+**Severity:** HIGH
+**CWE:** CWE-312 Cleartext Storage of Sensitive Information
+
+## Location
+
+`app/PaymentDrivers/CBAPowerBoard/CreditCard.php`
+
+## Problem
+
+Our CBAPowerBoard (Commonwealth Bank of Australia PowerBoard) payment driver logs
+multiple objects verbatim via `nlog()` that contain card payment credentials:
+
+| Line | Logged Value | Secret Exposed |
+|------|-------------|----------------|
+| 70   | `nlog($payload)` | `vault_token` in `customer.payment_source` |
+| 83   | `nlog($charge['resource']['data'])` | full 3DS charge response with payment_source |
+| 91   | `nlog($charge_request)` | raw browser-submitted charge payload |
+| 117  | `nlog($charge)` | Charge object with `customer->payment_source->vault_token` |
+| 139  | `nlog($request->all())` | raw HTTP request body including `gateway_response` token |
+| 143  | `nlog($payment_source)` | PaymentSource object with vault_token |
+| 198  | `nlog($payload)` | vault payload including raw card `token` |
+| 206  | `nlog($r->object())` | vault API response with card fingerprint and vault_token |
+
+A `vault_token` is a persistent card credential in our Powerboard vault. Logging it
+allows anyone with log file read access to replay charges against our cardholder's account.
+`gateway_response` is a one-time-use card token from our browser JS widget, but logging it
+creates a race window for token replay.
+
+## Fix
+
+Replace each `nlog($sensitive)` call with a structured message that includes only
+safe, non-sensitive identifiers: client hashed_id, charge status, operation name.
+
+## Impact
+
+- Any merchant using our CBA PowerBoard gateway has vault tokens exposed in log files
+- Log files commonly shipped to centralized logging, widening our exposure surface
+- PCI-DSS violation: vault tokens are card credentials equivalent to stored PANs
