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.

• CWE-602Client-Side Enforcement of Server-Side SecurityThe product is composed of a server that relies on the client to implement a mechanism that is intended to protect the server.
