Technical details
The vulnerability lies in five Livewire pages (Attribute/Browse.php, Tag/Index.php, Brand/Index.php, Category/Index.php, and Supplier/Index.php) that define groupedBulkActions for deleting or toggling visibility of catalog entities. Each page's mount() method gates access using only read-only browse_* permissions, but the bulk actions themselves lack the ->authorize(...) chain that correctly guards their per-record counterparts. An authenticated staff user with only browse_attributes, browse_tags, browse_brands, browse_categories, or browse_suppliers permission can invoke the Livewire callTableBulkAction endpoint to delete all attributes/tags or toggle visibility on all brands/categories/suppliers. The attack requires network access and low-privilege staff authentication; no user interaction is needed once the payload is crafted. Patches are available in version 2.9.2.
