ASGI requests with a missing or understated `Content-Length` header can bypass the `FILE_UPLOAD_MAX_MEMORY_SIZE` limit, potentially loading large files into memory and causing service degradation.\n \nAs a reminder, Django expects a limit to be configured at the web server level rather than solely relying on `FILE_UPLOAD_MAX_MEMORY_SIZE`. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.\n\nDjango thanks Kyle Agronick for reporting this issue.","affected":[{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0"},{"fixed":"6.0.5"}]}],"versions":["6.0","6.0.1","6.0.2","6.0.3","6.0.4"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-w26r-rmm8-9c29/GHSA-w26r-rmm8-9c29.json"}},{"package":{"name":"django","ecosystem":"PyPI","purl":"pkg:pypi/django"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.2"},{"fixed":"5.2.14"}]}],"versions":["5.2","5.2.1","5.2.10","5.2.11","5.2.12","5.2.13","5.2.2","5.2.3","5.2.4","5.2.5","5.2.6","5.2.7","5.2.8","5.2.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-w26r-rmm8-9c29/GHSA-w26r-rmm8-9c29.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-5766"},{"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-2026-54.yaml"},{"type":"WEB","url":"https://groups.google.com/g/django-announce"},{"type":"WEB","url":"https://www.djangoproject.com/weblog/2026/may/05/security-releases"}],"database_specific":{"cwe_ids":["CWE-130"],"github_reviewed":true,"github_reviewed_at":"2026-05-08T22:14:39Z","nvd_published_at":"2026-05-05T16:16:17Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
