In the module "Cross Selling in Modal Cart" (motivationsale) < 3.5.0 from MyPrestaModules for PrestaShop, a guest can perform SQL injection. The method `motivationsaleDataModel::getProductsByIds()` has sensitive SQL calls that can be executed with a trivial http call and exploited to forge a SQL injection.
