When pasting a <style> tag from the clipboard into a rich text
editor, the CSS sanitizer does not escape < and > characters. Because
the resulting string is pasted directly into the text node of the element
this does not result in a direct injection into the webpage; however, if a
webpage subsequently copies the node’s innerHTML, assigning it to another
innerHTML, this would result in an XSS vulnerability. Two WYSIWYG editors
were identified with this behavior, more may exist. This vulnerability
affects Firefox ESR < 68.4 and Firefox < 72.
