Complete validate_template_name() implementation to prevent LFI attacks by Copilot · Pull Request #1459 · InvoicePlane/InvoicePlane

Copilot · 2026-02-16T11:51:03Z

Problem

Critical LFI vulnerability (CVSS 9.1) allowed authenticated admins to execute arbitrary code by setting public_invoice_template to paths like ../../../logs/log-2026-01-30, enabling inclusion of poisoned log files.

Changes

The validate_template_name() function in application/helpers/template_helper.php was declared but not implemented - only the docblock and closing brace existed.

Completed implementation:

function validate_template_name($template_name, $type = 'invoice', $scope = 'pdf')
{
    $CI = & get_instance();
    $CI->load->helper('file_security');
    $CI->load->model('invoices/mdl_templates');
    
    // Get filesystem-based whitelist of valid templates
    if ($type === 'invoice') {
        $valid_templates = $CI->mdl_templates->get_invoice_templates($scope);
    } elseif ($type === 'quote') {
        $valid_templates = $CI->mdl_templates->get_quote_templates($scope);
    } else {
        $safe_type = sanitize_for_logging((string) $type);
        log_message('error', 'Template validation failed: Invalid template type: ' . $safe_type);
        return false;
    }
    
    // Strict whitelist validation - no path traversal possible
    if (!in_array($template_name, $valid_templates, true)) {
        $safe_template_name = sanitize_for_logging((string) $template_name);
        log_message('error', 'Template validation failed: Template not in allowed list: ' . $safe_template_name);
        return false;
    }
    
    return $template_name;
}

Security mechanism:

Whitelist validation against actual filesystem templates (no user paths allowed)
Strict in_array() comparison prevents type juggling
sanitize_for_logging() prevents secondary log injection attacks
Returns validated name or false (never returns unsanitized user input)

This function is called by View::invoice() and View::quote() before template inclusion, breaking the LFI attack chain. Path traversal and log poisoning mitigations were already present in other controllers.
