{"id":"PYSEC-2025-1","details":"An issue was discovered in Django 5.1 before 5.1.5, 5.0 before 5.0.11, and 4.2 before 4.2.18. 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 are vulnerable, as is the django.forms.GenericIPAddressField form field. (The django.db.models.GenericIPAddressField model field is not affected.)","aliases":["BIT-django-2024-56374","CVE-2024-56374","GHSA-qcgg-j2x8-h9g8"],"modified":"2025-03-10T09:27:38.709591Z","published":"2025-01-14T19:15:32Z","references":[{"type":"ARTICLE","url":"https://www.djangoproject.com/weblog/2025/jan/14/security-releases/"},{"type":"WEB","url":"https://docs.djangoproject.com/en/dev/releases/security/"},{"type":"WEB","url":"https://groups.google.com/g/django-announce"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/01/14/2"}],"affected":[{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.1"},{"fixed":"5.1.5"},{"introduced":"5.0"},{"fixed":"5.0.11"},{"introduced":"4.2"},{"fixed":"4.2.18"}]}],"versions":["4.2","4.2.1","4.2.10","4.2.11","4.2.12","4.2.13","4.2.14","4.2.15","4.2.16","4.2.17","4.2.2","4.2.3","4.2.4","4.2.5","4.2.6","4.2.7","4.2.8","4.2.9","5.0","5.0.1","5.0.10","5.0.2","5.0.3","5.0.4","5.0.5","5.0.6","5.0.7","5.0.8","5.0.9","5.1","5.1.1","5.1.2","5.1.3","5.1.4"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/django/PYSEC-2025-1.yaml"}}],"schema_version":"1.7.3"}
