Vulnerability Title
Header injection possibility since DomainNameValidator accepted newlines in input
Source: NVD (National Vulnerability Database)
Vulnerability Description
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 输入验证错误漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Django是Django团队开源的一套基于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 6.0.7之前版本和5.2.16之前版本存在输入验证错误漏洞，该漏洞源于DomainNameValidator未禁止域名中的换行符，如果应用将含换行符的值用于HTTP响应，可能导致标头注入。
