  "summary" : "Snipe-IT: Maintenance Record Disclosure via Missing Authorization on GET",
  "details" : "### Impact\nAny activated account in a company can read every maintenance record for that company (asset tag, supplier, purchase cost, free-text notes, dates) without holding any asset or maintenance permission.\n\n## Summary\n\n`MaintenancesController::show()` renders a maintenance record without any authorization check. Every other action in the controller authorizes against the asset; `show()` does not. Any user in the asset's company can read maintenance detail (asset tag, supplier, purchase cost, notes, dates) by visiting `/maintenances/{id}`, regardless of permissions.\n\n## Details\n\n```php\npublic function show(Maintenance $maintenance): View|RedirectResponse\n{\n    return view('maintenances.view')->with('maintenance', $maintenance);\n}\n```\n\nNo `authorize()` call. The sibling actions all gate on the asset: `index()` calls `authorize('view', Asset::class)` (line 33), and `edit()`/`update()`/`destroy()` call `authorize('update', $maintenance->asset)` (lines 139, 166, 286). The route is registered with only the auth guard:\n\n```php\nRoute::resource('maintenances', MaintenancesController::class, ['middleware' => ['auth']]);\n```\n\n(`routes/web/hardware.php:185`). Route-model binding still applies the company scope, so the read is bounded to the caller's company; the absent permission gate is the defect. Maintenance IDs are sequential and visible in the record URL.\n\n## Proof of concept\n\n1. As an administrator, create an asset in a company (here, `CompanyA`). Open the asset, choose Maintenances > Create, and add a record: name `MntA2`, supplier `SupA`, a purchase cost, and notes. The saved record opens at `/maintenances/{id}`.\n2. As the administrator, create a test user assigned to CompanyA, with **every permission left unchecked**. Activate the account.\n3. In a separate browser session, log in as the test user. Confirm it is unprivileged: the Assets and Maintenances navigation items are absent, and browsing to `/hardware` returns 403.\n4. In the address bar, browse to `http://<host>/maintenances/{id}`.\n\nObserved: the maintenance view renders in full for the unprivileged account.\n\n```\nGET /maintenances/5      ->  HTTP 200 OK\nRenders the \"Maintenance\" detail page for MntA2:\n  Asset: AssetA   Supplier: SupA   Cost: <value>   Notes: <text>   Dates: <...>\n\nGET /hardware            ->  HTTP 403  (same account, asset list is gated)\nGET /maintenances        ->  HTTP 403  (same account, maintenance list is gated)\nGET /maintenances/2      ->  HTTP 302  (record in CompanyB; company scope still hides it)\n```\n\n- The `test` account holds zero permissions and still reads the record.\n- Only the unguarded `show` route leaks: the list view and the asset pages return 403 for the same account.\n- A maintenance in a different company (CompanyB) redirects away, confirming the FMCS company scope still holds.\n\n### Patches\nPatched in https://github.com/grokability/snipe-it/commit/69c50aa2aee25f837626556b4f4f3d05ec7ace96",
