DescriptionCVE.org

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.

AnalysisAI

Price allowlist bypass in WPC Name Your Price for WooCommerce (WordPress plugin before 2.2.5) permits unauthenticated visitors to submit arbitrary below-minimum prices for products configured in "Select" mode, resulting in real completed orders at merchant-disadvantageous amounts and direct revenue loss. The flaw is a distinct business logic failure left unaddressed by the CVE-2025-12115 patch (v2.2.0), which only corrected a related but separate vector involving products with Name Your Price disabled. …
