From e6b3cae67c0fa162806c65dcee19a64156261b5f Mon Sep 17 00:00:00 2001 From: Snider <631881+Snider@users.noreply.github.com> Date: Wed, 4 Feb 2026 17:47:15 +0000 Subject: [PATCH 1/4] Security: Add workspace context and authorization to CreateCoupon tool Summary of changes: - Added `declare(strict_types=1);` to `src/Mcp/Tools/Commerce/CreateCoupon.php` for strict typing. - Implemented `RequiresWorkspaceContext` trait in `CreateCoupon` tool to enforce workspace scoping. - Updated `handle` method to retrieve workspace from authenticated context. - Added authorization check to ensure only workspace admins or owners (or API keys with proper context) can create coupons. - Scoped coupon existence check and creation to the authenticated workspace by including `workspace_id`. Note: Automated tests could not be executed due to missing environment dependencies (host-uk/core), but changes were manually verified against existing patterns in the codebase. --- src/Mcp/Tools/Commerce/CreateCoupon.php | 31 ++++++++++++++++++++++--- 1 file changed, 28 insertions(+), 3 deletions(-) diff --git a/src/Mcp/Tools/Commerce/CreateCoupon.php b/src/Mcp/Tools/Commerce/CreateCoupon.php index 04385b2..4714ef4 100644 --- a/src/Mcp/Tools/Commerce/CreateCoupon.php +++ b/src/Mcp/Tools/Commerce/CreateCoupon.php @@ -1,8 +1,11 @@ getWorkspace(); + $user = auth()->user(); + + // Verify the caller has permission (admin role check) + $isHades = method_exists($user, 'isHades') && $user->isHades(); + $isWorkspaceAdmin = $user && $workspace->users() + ->where('user_id', $user->id) + ->whereIn('role', ['admin', 'owner']) + ->exists(); + + // If authenticated via API key, we trust the key has proper workspace access + // but we still want to ensure it's not a restricted key if possible. + if (! $isHades && ! $isWorkspaceAdmin && ! $request->attributes->has('api_key')) { + return Response::text(json_encode([ + 'error' => 'Unauthorized.
