Descriptions

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.

En Django 3.2 anterior a 3.2.25, 4.2 anterior a 4.2.11 y 5.0 anterior a 5.0.3, el método django.utils.text.Truncator.words() (con html=True) y el filtro de plantilla truncatewords_html están sujetos a un potencial Ataque de denegación de servicio de expresión regular a través de una cadena manipulada. NOTA: este problema existe debido a una solución incompleta para CVE-2019-14232 y CVE-2023-43665.

An inefficient regular expression complexity flaw was found in the Truncator.words function and truncatewords_html filter of Django. This issue may allow an attacker to use a suitably crafted string to cause a denial of service.
