CVE-2026-59536Network attack vector

Arbitrary cart pricing via unauthenticated price override

Published Jul 27, 2026 · Updated Jul 27, 2026

Missing authorization in CoCart 4.8.4 and earlier allows remote attackers to set arbitrary cart item prices through REST requests. The public cocart/v2/cart/add-item route honors its price parameter by default, allowing the caller to override the product price used for the cart. No account or user interaction is required; the change affects an attacker-controlled cart and can carry into order totals.
