"The detected version of the Django Python package, Django, is 4.2.x prior to 4.2.18, 5.0.x prior to 5.0.11 or 5.1.x prior to 
5.1.5. It is, therefore, affected by a denial of service vulnerability as disclosed in Django's January 14th 2025 security
advisory. A lack of upper bound limit enforcement in strings passed when performing IPv6 validation could lead to a potential 
denial-of-service attack. The undocumented and private functions clean_ipv6_address and is_valid_ipv6_address were vulnerable, 
as was the django.forms.GenericIPAddressField form field, which has now been updated to define a max_length of 39 characters.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
