/upload/catalog/controller/account/password.php in OpenCart through 3.0.2.0 has CSRF via the index.php?route=account/password URI to change a user's password.

OpenCart through 3.0.2.0 allows directory traversal in the editDownload function in admin\model\catalog\download.php via admin/index.php?route=catalog/download/edit, related to the download_id. For example, an attacker can download ../../config.php.

The "program extension upload" feature in OpenCart through 3.0.2.0 has a six-step process (upload, install, unzip, move, xml, remove) that allows attackers to execute arbitrary code if the remove step is skipped, because the attacker can discover a secret temporary directory name (containing 10 random digits) via a directory traversal attack involving language_info['code'].

The Cart::getProducts method in system/library/cart.php in OpenCart 1.5.6.4 and earlier allows remote attackers to conduct server-side request forgery (SSRF) attacks or possibly conduct XML External Entity (XXE) attacks and execute arbitrary code via a crafted serialized PHP object, related to the quantity parameter in an update request.

SQL injection vulnerability in the updateAmazonOrderTracking function in upload/admin/model/openbay/amazon.php in OpenCart before version 2.3.0.0 allows remote authenticated administrators to execute arbitrary SQL commands via a carrier (aka courier_id) parameter to openbay.php.

Cross-site scripting (XSS) vulnerability in OpenCart before 2.1.0.2 allows remote attackers to inject arbitrary web script or HTML via the zone_id parameter to index.php.
