[QUESTION] How to sanitize style tags and attributes #808

Closed JeremyBradshaw7 closed 1 year ago

JeremyBradshaw7 commented 1 year ago

I plan to allow style tags and attributes through, but I do want to strip out any security vulnerabilities from them, such as any expression or javascript: use as discussed here.

How can that be achieved in dompurify?

Why? Is MSIE6 part of your threat model? If so, DOMPurify won't work anyway and for no other browser, those kinds of sanitizations are actually needed.
