 "title": "Welcart e-Commerce <= 2.12.6 - Unauthenticated Arbitrary Shortcode Execution via Inquiry Form",
 "description": "The Welcart e-Commerce plugin for WordPress is vulnerable to Arbitrary Shortcode Execution via the inquiry form in all versions up to, and including, 2.12.6 due to the sender-supplied inquiry content being passed through do_shortcode when building the customer and manager inquiry e-mails. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The sender's input was also inserted unescaped into HTML inquiry mails, allowing HTML injection.",
