Overview
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the django.utils.text.Truncator.chars and Truncator.words methods (when html=True), as well as the truncatechars_html and truncatewords_html template filters, when processing crafted input containing a large number of unmatched HTML end tags. An attacker can cause excessive resource consumption by submitting such specially crafted input.
