Why precisely the twig raw filter is insecure in the drupal context?

What would be an example of a potential threat ?

And what need to be done on the ckeditor field format side to protect potential malicious code, if the raw filter is used ?

Twig templates escape special characters to prevent potential hacking. Twig raw puts out the data without escaping it, meaning that if it is user-supplied data, it's insecure and could be used for hacking.

    There are multiple levels of filters. Twig filters are just one of them.

    @Matoeil, when you have filtered with a text format you don't need |raw because the filtered markup is already marked as safe.
