CyberRota Analysis

AI-Generated

Craft Commerce versions 4.0.0 to 4.11.2 and 5.6.5 are vulnerable to a rate-limiting bypass in the CartController, allowing unauthenticated attackers to exploit the couponCode parameter for unlimited automated guessing and enumeration of coupon codes. This could lead to unauthorized discounts or financial loss for affected ecommerce platforms. Organizations using these versions should prioritize upgrading to 4.11.2 or 5.6.5 to mitigate this risk.

Original NVD Description

Craft Commerce is an ecommerce platform for Craft CMS. From 4.0.0 until 4.11.2 and 5.6.5, CartController in src/controllers/CartController.php activates its RateLimiter only when the number POST or GET parameter is supplied. An unauthenticated attacker can submit couponCode values to actionUpdateCart for the session-based cart while omitting number, preventing creation of the IP rate-limit identity and allowing unlimited automated coupon-code guessing and enumeration. This issue is fixed in versions 4.11.2 and 5.6.5.
