Craft Commerce vulnerabilities

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.

An SQL injection vulnerability in Craft Commerce (versions 5.0.0-5.5.4) exists in the ProductQuery::hasVariant and VariantQuery::hasProduct properties, which bypass the sanitization blocklist. An authenticated control panel user can exploit boolean-based blind SQL injection to extract arbitrary database contents, including security keys that enable forging admin sessions.

An SQL injection vulnerability in Craft Commerce (versions 4.0.0-4.10.2 and 5.0.0-5.5.4) in the Commerce TotalRevenue widget allows any authenticated control panel user to achieve remote code execution through a four-step exploitation chain. The attack exploits unsanitized widget settings and PDO's default multi-statement support to inject a maliciously serialized PHP object into the queue table.
