Due to the behavior of the underlying HTMLParser, :func:django.utils.html.strip_tags would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities. The strip_tags() method is used to implement the corresponding:tfilter:striptags template filter, which was thus also vulnerable.
