Prior to 7.0.2, S3FileMiddleware is vulnerable to relative path traversal attacks, where an attacker can use a modified request to escape pre-signed upload locations and have the Django application load files from random locations into request.FILES. Depending on how files are handled, this may lead to confidentiality and integrity issues. This vulnerability is fixed in 7.0.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","score":9.9},"cvss_v3":null,"cwes":["CWE-22","CWE-26"],"references":["https://github.com/codingjoe/django-s3file/security/advisories/GHSA-67qg-7284-2277"],"products":[],"source":"nvd","synced_at":"2026-10-26T14:27:29.784594657+00:00"},"epss":{"cve":"CVE-2026-42196","score":0.00565,"percentile":0.46664,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-67qg-7284-2277","url":"https://osv.dev/vulnerability/GHSA-67qg-7284-2277","summary":"django-s3file is vulnerable to relative path traversal","modified":"2026-06-29T12:26:48.189409964Z","packages":[{"ecosystem":"PyPI","name":"django-s3file","purl":"pkg:pypi/django-s3file","ranges":["<7.0.2"],"fixed":["7.0.2"]}]},{"id":"PYSEC-2026-328","url":"https://osv.dev/vulnerability/PYSEC-2026-328","summary":"django-s3file is vulnerable to relative path traversal","modified":"2026-07-13T16:15:23.624771324Z","packages":[{"ecosystem":"PyPI","name":"django-s3file","purl":"pkg:pypi/django-s3file","ranges":["<7.0.2"],"fixed":["7.0.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
