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.)","published":"2025-01-14T00:00:00Z","modified":"2026-08-12T03:51:08.893868432Z","cvss":{"score":5.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"django","fixedVersion":"5.1.5"},{"ecosystem":"PyPI","name":"django","fixedVersion":"5.0.11"},{"ecosystem":"PyPI","name":"django","fixedVersion":"4.2.18"},{"ecosystem":"PyPI","name":"django","fixedVersion":"5.1.5"},{"ecosystem":"PyPI","name":"django","fixedVersion":"5.0.11"},{"ecosystem":"PyPI","name":"django","fixedVersion":"4.2.18"}],"fix":{"url":"https://github.com/django/django/commit/4806731e58f3e8700a3c802e77899d54ac6021fe","label":"django/django@4806731"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/01/14/2"},{"type":"WEB","url":"https://docs.djangoproject.com/en/dev/releases/security/"},{"type":"WEB","url":"https://groups.google.com/g/django-announce"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00024.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56374.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-56374"},{"type":"ARTICLE","url":"https://www.djangoproject.com/weblog/2025/jan/14/security-releases/"},{"type":"WEB","url":"https://github.com/django/django/commit/4806731e58f3e8700a3c802e77899d54ac6021fe"},{"type":"WEB","url":"https://github.com/django/django/commit/ad866a1ca3e7d60da888d25d27e46a8adb2ed36e"},{"type":"WEB","url":"https://github.com/django/django/commit/ca2be7724e1244a4cb723de40a070f873c6e94bf"},{"type":"WEB","url":"https://github.com/django/django/commit/e8d4a2005955dcf962193600b53bf461b190b455"},{"type":"WEB","url":"https://docs.djangoproject.com/en/dev/releases/security"},{"type":"PACKAGE","url":"https://github.com/django/django"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/django/PYSEC-2025-1.yaml"},{"type":"WEB","url":"https://www.djangoproject.com/weblog/2025/jan/14/security-releases"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:08.893868432Z"}}
