## Overview

In Django 3.2 before 3.2.25, 4.2 before 4.2.11, and 5.0 before 5.0.3, the django.utils.text.Truncator.words() method (with html=True) and the truncatewords_html template filter are subject to a potential regular expression denial-of-service attack via a crafted string. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232 and CVE-2023-43665.

## Affected packages

- `django >= 3.2, < 3.2.25`
- `django >= 4.2, < 4.2.11`
- `django >= 5.0, < 5.0.3`

## Remediation

Upgrade to a patched release:

- `django 3.2.25`
- `django 4.2.11`
- `django 5.0.3`
