Vulnerability CVE-2019-14232

Vulnerability Name:

CVE-2019-14232 (CCN-164681)

Assigned:

2019-08-01

Published:

2019-08-01

Updated:

2020-08-24

Summary:

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.
