 "title": "Strong Testimonials <= 3.3.12 - Authenticated (Subscriber+) Arbitrary Shortcode Execution via Form Preview",
 "description": "The Strong Testimonials plugin for WordPress is vulnerable to Arbitrary Shortcode Execution via the 'wpmtst_get_form_preview' AJAX action in all versions up to, and including, 3.3.12. This is due to a missing capability check: the handler only verifies the 'wpmtst-admin' nonce, which the plugin prints on every admin page for every logged-in user, and it then renders user-supplied field definitions, passing the 'shortcode_on_form' value to do_shortcode() and an 'action_input' value to do_action(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes and trigger arbitrary action hooks.",
