An update for python-django is now available for openEuler-24.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-2218 Final 1.0 1.0 2026-05-09 Initial 2026-05-09 2026-05-09 openEuler SA Tool V1.0 2026-05-09 python-django security update An update for python-django is now available for openEuler-24.03-LTS A high-level Python Web framework that encourages rapid development and clean, pragmatic design. Security Fix(es): An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. `MultiPartParser` allows remote attackers to degrade performance by submitting multipart uploads with `Content-Transfer-Encoding: base64` including excessive whitespace. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Seokchan Yoon for reporting this issue.(CVE-2026-33033) An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. ASGI requests with a missing or understated Content-Length header could bypass the DATA_UPLOAD_MAX_MEMORY_SIZE limit when reading HttpRequest.body, allowing remote attackers to load an unbounded request body into memory. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Superior for reporting this issue.(CVE-2026-33034) This issue was discovered in version 6.0, before 6.0.5, and before 5.2.14. If the session has not been modified, the cookie's response header does not change, but "SESSION_SAVE_EVERY_REQUEST" is "true". A remote attacker could steal a user's session after the user visits a cached public page. Earlier unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) have not been evaluated and may also be affected. Django thanks Cantina for reporting this issue.(CVE-2026-35192) An issue was discovered in Django versions 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. ASGIRequest allows a remote attacker to spoof headers by exploiting an ambiguous mapping of two header variants (with hyphens or with underscores) to a single version with underscores. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.(CVE-2026-3902) An issue was discovered in Django's GenericInlineModelAdmin component. Add permissions on inline model instances were not validated on submission of forged POST data. This vulnerability affects Django 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank N05ec@LZU-DSLab for reporting this issue.(CVE-2026-4277) An issue was discovered in Django 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. Admin changelist forms using ModelAdmin.list_editable incorrectly allowed new instances to be created via forged POST data. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Cantina for reporting this issue.(CVE-2026-4292) When processing ASGI requests, if the Content-Length request header is deliberately omitted in a malicious request, or a false value is provided that is much smaller than the actual file, the system will be deceived, thereby bypassing Django's built-in FILE_UPLOAD_MAX_MEMORY_SIZE (maximum memory file upload limit)(CVE-2026-5766) 处理 ASGI 请求时，如果请求中缺少 Content-Length 请求头，或者人为提供了偏小的数值，就能绕过 Django 内置的 FILE_UPLOAD_MAX_MEMORY_SIZE（最大内存文件上传大小）限制(CVE-2026-6907) An update for python-django is now available for master/openEuler-20.03-LTS-SP4/openEuler-22.03-LTS-SP4/openEuler-24.03-LTS/openEuler-24.03-LTS-Next/openEuler-24.03-LTS-SP1/openEuler-24.03-LTS-SP2/openEuler-24.03-LTS-SP3/openEuler-24.03-LTS-SP4. openEuler Security has rated this update as having a security impact of critical.
