Description
The Advanced Form Integration plugin for WordPress is vulnerable to Arbitrary Shortcode Execution via form submission values in all versions up to, and including, 2.10.3. This is due to the adfoin_get_parsed_values() function substituting user-submitted form values into integration field templates and then passing the result to do_shortcode() without neutralizing square brackets in those values. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes by submitting them through a front-end form that is connected to an active integration, which may trigger side effects or expose data through shortcodes registered by other plugins.
