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":"2026-07-15T10:14:37.278552568Z","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":null,"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/"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T10:14:37.278552568Z"}}
