Description Guilherme de Almeida Suckevicz 2020-01-21 19:00:06 UTC 
In WordPress before 5.3.1, authenticated users with lower privileges (like contributors) can inject JavaScript code in the block editor, which is executed within the dashboard. It can lead to an admin opening the affected post in the editor leading to XSS.
