An update for python-django is now available for openEuler-20.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-3074 Final 1.0 1.0 2026-07-19 Initial 2026-07-19 2026-07-19 openEuler SA Tool V1.0 2026-07-19 python-django security update An update for python-django is now available for openEuler-20.03-LTS-SP4 A high-level Python Web framework that encourages rapid development and clean, pragmatic design. Security Fix(es): 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 5.2 before 5.2.15 and 6.0 before 6.0.6. `django.middleware.cache.UpdateCacheMiddleware` in Django does not add `Authorization` to the `Vary` response header for requests bearing that header without `Cache-Control: public`, which allows remote attackers to read private cached responses via unauthenticated requests to the same URL. 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 Shai Berger for reporting this issue.(CVE-2026-35193) An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6. `django.utils.cache.has_vary_header()` in Django does not strip leading or trailing whitespace from `Vary` response header values before comparison, which allows remote attackers to read cached responses via requests to URLs whose responses contain whitespace-padded Vary header values. 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 Navid Rezazadeh for reporting this issue.(CVE-2026-48587) An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `UpdateCacheMiddleware` and the `cache_page()` decorator cache responses that vary on cookies when the incoming request carries unrelated cookies, which allows remote attackers to read private data from the shared cache. 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 Chris Whyland for reporting this issue.(CVE-2026-48588) An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `django.contrib.gis.gdal.GDALRaster` over-reads its in-memory buffer when constructed from a bytes object, which can disclose adjacent memory or cause service degradation via a potential segmentation fault when the `vsi_buffer` property is accessed. 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 Bence Nagy for reporting this issue.(CVE-2026-53877) 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) An issue was discovered in Django 6.0 before 6.0.6 and 5.2 before 5.2.15. `django.http.HttpRequest.get_signed_cookie` in Django uses a non-injective salt derivation (concatenating the cookie name and salt argument), which allows a remote attacker to use a cookie in a context different from the one where it was signed, via distinct `(name, salt)` pairs that produce the same concatenation. 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 Peng Zhou for reporting this issue.(CVE-2026-6873) 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 issue was discovered in Django 6.0 before 6.0.6 and 5.2 before 5.2.15. `django.core.mail.backends.smtp.EmailBackend` in Django fails to prevent reuse of a partially-initialized connection after a failed `STARTTLS` handshake when `fail_silently=True`, which allows on-path network attackers to read email content via cleartext interception. 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 Kasper Dupont for reporting this issue.(CVE-2026-7666) An issue was discovered in Django 5.2 before 5.2.15 and 6.0 before 6.0.6. `django.middleware.cache.UpdateCacheMiddleware` in Django does not match `Cache-Control` response directives case-insensitively, which allows remote attackers to read responses that were incorrectly cached because their `Cache-Control` directives used uppercase or mixed-case values. 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 Ahmed Badawe for reporting this issue.(CVE-2026-8404) An update for python-django is now available for openEuler-20.03-LTS-SP4. openEuler Security has rated this update as having a security impact of medium.
