Malicious actors are exploiting a previously unknown security flaw in the open source PrestaShop e-commerce platform to inject malicious skimmer code designed to swipe sensitive information. "Attackers have found a way to use a security vulnerability to carry out arbitrary code execution in servers running PrestaShop websites," the company noted in an advisory published on July 22. PrestaShop is marketed as the leading open-source e-commerce solution in Europe and Latin America, used by nearly 300,000 online merchants worldwide.
