Unauthenticated sales disclosure via over-fetching REST route
Published Aug 6, 2026 · Updated Aug 6, 2026
Information disclosure in WPDeveloper Essential Blocks before 6.4.0 allows remote attackers to read product lifetime sales data. The public essential-blocks/v1/products REST route performs no access check and returns WooCommerce total_sales as sold_count for published products. No authentication, cookie, or nonce is required; exposure is limited to published products and their lifetime unit counts.
