## Summary Five Filament `groupedBulkActions` blocks across the Shopper admin Livewire pages omit the `->authorize(...)` permission gate, while their per-record sibling actions (and other Shopper Index pages such as `Pages/Settings/Currencies.php`, `Pages/Reviews/Index.php`, `Pages/Collection/Index.php`, and `Pages/Discount/Index.php`) correctly chain `->authorize(...)`. Each affected page's `mount()` only requires the read-only `browse_*` permission, so a low-privilege staff user holding only the read permission can drive the bulk endpoint via the standard Livewire `callTableBulkAction` flow and execute state-mutating operations they were never granted. The vulnerability is the same class as GHSA-f946-9qp6-vgch and GHSA-j328-xmgp-j4q3 (read-only permission gating a write action), just on a different surface (Filament 4 `groupedBulkActions` rather than top-level Livewire methods). A staff user holding only `browse_attributes` can permanently delete every product attribute in the catalog (cascading break of every dependent product variant). A user holding only `browse_tags` can permanently delete every product tag. Users holding `browse_brands`, `browse_categories`, or `browse_suppliers` can flip the visibility (`is_enabled`) of every brand/category/supplier in bulk, sabotaging storefront catalog visibility. CVSS 3.1: `AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H` = 8.1 High. CWE-285 (Improper Authorization) and CWE-862 (Missing Authorization). The attacker has low privilege (browse-only staff role), no user interaction, network reachable. ## Vulnerable components (paths relative to repo root) All references are HEAD = commit `ac9a760` on `master` (the very commit that closed the previous wave of authorization-drift bugs from GHSA-j328-xmgp-j4q3). ### 1) `packages/admin/src/Livewire/Pages/Attribute/Browse.php` Mount at line 36–39 requires only `browse_attributes`. - Lines 106–122: `DeleteBulkAction::make()` has NO `->authorize(...)` chain (the surrounding per-record `delete` action at lines 95–104 correctly does `->authorize('delete_attributes')`). - Lines 123–138: `BulkAction::make('enabled')` has NO `->authorize(...)`. - Lines 139–155: `BulkAction::make('disabled')` has NO `->authorize(...)`. Net effect: a `browse_attributes`-only user can **delete every row in the attributes table**, and toggle `is_enabled` on every attribute in one request. Deleting an attribute cascades into every product variant that references it via the `attribute_product` pivot. ### 2) `packages/admin/src/Livewire/Pages/Tag/Index.php` Mount at line 39 requires only `browse_tags`. - Lines 96–108: `DeleteBulkAction::make()` has NO `->authorize(...)` chain (the per-record `delete` action at lines 79–94 correctly does `->authorize('delete_tags')`). Net effect: a `browse_tags`-only user can delete every `ProductTag` row. ### 3) `packages/admin/src/Livewire/Pages/Brand/Index.php` Mount at line 37–40 requires only `browse_brands`. - Lines 97–112: `BulkAction::make('enabled')` has NO `->authorize(...)`. - Lines 113–129: `BulkAction::make('disabled')` has NO `->authorize(...)`. Net effect: a `browse_brands`-only user can flip `is_enabled` on every brand. Disabling all brands removes them from the storefront catalog. The per-record edit/delete actions and the `DeleteBulkAction` at lines 130–148 are correctly `->authorize(...)` gated — only the visibility bulk actions were missed. ### 4) `packages/admin/src/Livewire/Pages/Category/Index.php` Mount at line 38–41 requires only `browse_categories`. - Lines 102–117: `BulkAction::make('enabled')` has NO `->authorize(...)`. - Lines 118–133: `BulkAction::make('disabled')` has NO `->authorize(...)`. Net effect: a `browse_categories`-only user can flip `is_enabled` on every category. Same shape as Brand. ### 5) `packages/admin/src/Livewire/Pages/Supplier/Index.php` Mount at line 38 requires only `browse_suppliers`. - Lines 93–108: `BulkAction::make('enabled')` has NO `->authorize(...)`. - Lines 109–125: `BulkAction::make('disabled')` has NO `->authorize(...)`. Net effect: a `browse_suppliers`-only user can flip `is_enabled` on every supplier. ## Reference comparison: places that ARE correctly gated For reference, here is what the same pattern looks like in files that DID get the fix: - `packages/admin/src/Livewire/Pages/Settings/Currencies.php` lines 90–129: every `BulkAction` chains `->authorize('access_setting')`. - `packages/admin/src/Livewire/Pages/Reviews/Index.php` lines 105–119: `DeleteBulkAction` chains `->authorize('delete_reviews')`. - `packages/admin/src/Livewire/Pages/Collection/Index.php` lines 109–128: `DeleteBulkAction` chains `->authorize('delete_collections')`. - `packages/admin/src/Livewire/Pages/Discount/Index.php` lines 126–145: `DeleteBulkAction` chains `->authorize('delete_discounts')`. The convention is established and applied elsewhere — these five files just missed it. ## Proof of Concept The attached file `tests/Admin/Livewire/Pages/Brand/AuthBypassPocTest.php` (added in this report) contains seven Pest tests, each acting as a `browse_*`-only staff user and invoking the bulk endpoint. All seven pass on master @ `ac9a760`: ``` PASS Tests\Admin\Livewire\Pages\Brand\AuthBypassPocTest ✓ it SHOPPER-2 PoC: read-only viewer can mass-DISABLE all brands via unguarded BulkAction ✓ it SHOPPER-2 PoC: read-only viewer can mass-ENABLE all brands via unguarded BulkAction ✓ it SHOPPER-2 PoC: read-only viewer can mass-DISABLE all categories via unguarded BulkAction ✓ it SHOPPER-2 PoC: read-only viewer can mass-DISABLE all suppliers via unguarded BulkAction ✓ it SHOPPER-2 PoC: read-only viewer can DELETE all attributes via unguarded DeleteBulkAction ✓ it SHOPPER-2 PoC: read-only viewer can mass-DISABLE all attributes via unguarded BulkAction ✓ it SHOPPER-2 PoC: browse_tags viewer can DELETE all product tags via unguarded DeleteBulkAction Tests: 7 passed (32 assertions) ``` Each test seeds three records, signs in a user holding only the corresponding `browse_*` permission, calls `Livewire::test(<Page>::class)->callTableBulkAction(...)`, and asserts the side effect (records flipped or deleted). For example, the attribute mass-delete test: ```php $this->viewer = User::factory()->create(); $this->viewer->givePermissionTo('browse_attributes'); $this->actingAs($this->viewer); Attribute::factory()->count(3)->create(); expect($this->viewer->can('delete_attributes'))->toBeFalse(); Livewire::test(AttributeBrowse::class) ->callTableBulkAction(\Filament\Actions\DeleteBulkAction::class, Attribute::pluck('id')->toArray()) ->assertHasNoErrors(); expect(Attribute::count())->toBe(0); ``` The call uses the same `callTableBulkAction` helper Shopper's own test suite uses everywhere, which in turn drives the same Livewire `update` payload the browser would emit — so this is a faithful HTTP-level reproduction. ## Suggested fix Add `->authorize(<correct_permission>)` to each of the five vulnerable groups, mirroring the pattern already used elsewhere: ```diff // Pages/Attribute/Browse.php ->groupedBulkActions([ DeleteBulkAction::make() + ->authorize('delete_attributes') ->label(__('shopper::forms.actions.delete')) ->requiresConfirmation() ->action(function (Collection $records): void { /* ... */ }), BulkAction::make('enabled') + ->authorize('edit_attributes') ->label(__('shopper::forms.actions.enable')) ->action(function (Collection $records): void { /* ... */ }), BulkAction::make('disabled') + ->authorize('edit_attributes') ->label(__('shopper::forms.actions.disable')) ->action(function (Collection $records): void { /* ... */ }), ]) ``` Apply the equivalent change to `Pages/Tag/Index.php` (`delete_tags`), `Pages/Brand/Index.php` (`edit_brands` for enable/disable), `Pages/Category/Index.php` (`edit_categories`), and `Pages/Supplier/Index.php` (`edit_suppliers`). A regression test for each file (acting as a `browse_*`-only user and expecting `assertHasErrors`/`AuthorizationException`) would lock in the fix, matching the regression tests added for #514. ## Resources - Prior advisories of the same class (read-only permission gating a write action): GHSA-f946-9qp6-vgch, GHSA-j328-xmgp-j4q3 / GHSA-vw82-3966-f9mr. - Same-shape fix: commit `ac9a760` (PR #514). Five Filament bulk-action groups did not receive the corresponding `->authorize(...)` chain. - CWE-285 Improper Authorization, CWE-862 Missing Authorization. ### Credits Reported by Vishal Shukla(@shukla304) using sechub.dev AI Agent ### Support If this disclosure was useful and userswould like to support continued open-source security research and responsible-disclosure work, they can sponsor at https://github.com/sponsors/therawdev — Shopper is thankful for those keeping open source safe.
