Jetpack < 12.7 - Authenticated(Contributor+) Clickjacking via Iframe Injection

Description

The Jetpack – WP Security, Backup, Speed, & Growth plugin for WordPress is vulnerable to Clickjacking via iframe injection due to an unknown parameter in all versions up to and including 12.6.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access and above, to inject iframes in pages that can be used to make users perform actions on untrusted sites.
