If you have explicitly allowed the <style> tag, an attacker could craft HTML that includes script after passing through the sanitizer. The default settings disallow the <style> tag so there is no risk if you have not explicitly allowed the <style> tag.
The problem has been fixed in version 5.0.372.
Remove the <style> tag from the set of allowed tags.
