CVE-2026-33034— Potential denial-of-service vulnerability in ASGI requests via memory upload limit bypass

Potential denial-of-service vulnerability in ASGI requests via memory upload limit bypass

An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. ASGI requests with a missing or understated `Content-Length` header could bypass the `DATA_UPLOAD_MAX_MEMORY_SIZE` limit when reading `HttpRequest.body`, allowing remote attackers to load an unbounded request body into memory. 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 Superior 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 6.0.4之前版本、5.2.13之前版本和4.2.30之前版本存在安全漏洞，该漏洞源于缺少或低估Content-Length标头的ASGI请求可能绕过DATA_UPLOAD_MAX_MEMORY_SIZE限制，可能导致远程攻击者将无限请求体加载到内存中。
