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.

Affected: Packagist: craftcms/commerce

### Summary

The CartController defines a RateLimiter behavior that is only activated when the 'number' POST/GET parameter is explicitly provided.

### Details

When an attacker submits coupon codes against the session-based cart (without passing a 'number' parameter), no rate limiting is applied. This allows unlimited attempts to guess coupon codes.

### Impact An attacker can enumerate all coupon codes through automated requests.

**Remediation** Apply rate limiting unconditionally on actionUpdateCart regardless of whether 'number' is present.
