From fdfb03f55dae8a9b5b8c9a3cfd0043a9642b874c Mon Sep 17 00:00:00 2001 From: "Aaron K. Clark" Date: Tue, 19 May 2026 04:44:46 -0500 Subject: [PATCH] =?UTF-8?q?fix(inventoryitem):=20return=20404=20(not=20403?= =?UTF-8?q?)=20on=20cross-tenant=20access=20=E2=80=94=20close=20tenant-enu?= =?UTF-8?q?meration=20leak?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Same class of bug as #174 (company), #188 (billingtype), #192 (worker), applied to the InventoryItem controller's getById/update/remove handlers. A scoped (non-master) caller asking about an `invitId` belonging to another tenant got 403, while non-existent ids returned 404 — letting them iterate inventory-item ids and learn which are populated across the whole tenant table by status code alone. Collapse both cases into 404 with the same `"Not found."` body. Master-key callers see every item; own-tenant 200 path unchanged. Pinned in `tests/api/inventoryitem.test.js` as three controller-level unit tests (one per handler), driving the controller directly with stubbed `InventoryItem.findByPk` returning a row in tenant 99 while spying on `auth.isMaster` / `auth.getCompanyId` to make the caller appear scoped to tenant 7.
