CVE-2019-14232 (GCVE-0-2019-14232)

Vulnerability from cvelistv5 – Published: 2019-08-02 00:00 – Updated: 2024-08-05 00:12
VLAI
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.
