CVE-2026-6873— Django 安全漏洞

Signed cookie salt namespace collision in django.http.HttpRequest.get_signed_cookie

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.

Django 安全漏洞

Django是Django基金会的一套基于Python语言的开源Web应用框架。该框架包括面向对象的映射器、视图系统、模板系统等。 Django 6.0.6之前版本和5.2.15之前版本存在安全漏洞，该漏洞源于HttpRequest.get_signed_cookie使用非注入式盐值派生，可能导致cookie上下文混淆。
