 "title": "WPFunnels – Funnel Builder for WooCommerce with Checkout & One Click Upsell <= 3.13.5 - Missing Authorization to Unauthenticated Telemetry Opt-In/Opt-Out Change",
 "description": "The WPFunnels plugin for WordPress is vulnerable to unauthorized modification of data in all versions up to, and including, 3.13.5 due to the bundled telemetry consent handler running on admin_init without any login, capability or nonce check. This makes it possible for unauthenticated attackers to change the site's telemetry opt-in or opt-out setting via requests to admin-ajax.php or admin-post.php.",
