CVE-2019-14232 Information

Description

An issue was discovered in Django 1.11.x before 1.11.23 2.1.x before 2.1.11 and 2.2.x before 2.2.4. If django.utils.text.Truncator’s chars() and words() methods were passed the html=True argument they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters which were thus vulnerable.
