Django: has_vary_header may expose cached responses when Vary values contain whitespace

CVE-2026-48587 / GHSA-923m-gv2p-w5qp

More information

Details

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.

Django: GDALRaster may over-read heap memory when constructed from bytes

CVE-2026-53877 / GHSA-crhf-3pfg-w68w

More information

Details

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.

Django: cache middleware may expose private responses when unrelated request cookies are present

CVE-2026-48588 / GHSA-3h9f-r86x-qvjx

More information

Details

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.

Django: DomainNameValidator permits newline characters that may enable HTTP header injection

CVE-2026-53878 / GHSA-8qcx-xf44-272x

More information

Details

An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16.
DomainNameValidator does not prohibit newlines in domain names (unless used via a form field, since CharField strips newlines). If an application uses values with newlines in an HTTP response, header injection can occur. Django itself is unaffected because HttpResponse prohibits newlines in HTTP headers.
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.

Django: UpdateCacheMiddleware may disclose cached responses due to case-sensitive Cache-Control handling

CVE-2026-8404 / GHSA-8cjm-8mp7-r2xf

More information

Details

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.

Django: signed cookies are vulnerable to salt namespace collisions

CVE-2026-6873 / GHSA-h7pc-vwp9-298g

More information

Details

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.
