CVE-2026-48587— Django 安全漏洞

Potential exposure of private data via whitespace padding in Vary header

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 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 5.2 5.2.15之前版本和6.0 6.0.6之前版本存在安全漏洞，该漏洞源于has_vary_header未去除Vary响应标头值的前后空白，可能导致远程攻击者读取缓存响应。
