  - Cockpit (and its plugins) do not seem to protect itself against clickjacking. It is possible to render a
    page from a cockpit server via another website, inside an <iFrame> HTML entry. This may be used by a
    malicious website in clickjacking or similar attacks. (CVE-2021-3660)

advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
