 "title": "Forminator Forms <= 1.57.3 - Unauthenticated Arbitrary Shortcode Execution via User-Agent Header and Referer URL",
 "description": "The Forminator Forms plugin for WordPress is vulnerable to Arbitrary Shortcode Execution in all versions up to, and including, 1.57.3. When a quiz notification email contained the {quiz_result} tag, the plugin replaced request-controlled tags such as {user_agent}, {refer_url} and {http_refer} and then ran do_shortcode() on the whole message without removing shortcode syntax from those values. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes when completing a quiz whose notification uses these tags.",
