Description: Sylius through 2.3.0 contains an authorization bypass vulnerability that allows unauthenticated attackers to read unmoderated and rejected product reviews because the AcceptedExtension filter is not applied to the item operation. Attackers can enumerate sequential ids on GET /api/v2/shop/product-reviews/{id} to retrieve review titles, ratings, comments, timestamps and author first names, bypassing merchant moderation.
