CVE-2026-16620

Description

The WPC Name Your Price for WooCommerce WordPress plugin before 2.2.5 does not enforce its server-side price allowlist for products configured in -Select- price mode, allowing an unauthenticated visitor to add such a product to the cart at an arbitrary value below the merchant-defined allowed prices and commit a real order at that price (revenue loss / underpriced orders). This is a distinct, unfixed vector from CVE-2025-12115, whose 2.2.0 fix only addressed applying a custom price to products where Name Your Price is disabled and left the Select-mode allowlist unenforced through 2.2.4.
