CVE-2026-33034

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.

Summary		(es) Se descubrió un problema en 6.0 anterior a 6.0.4, 5.2 anterior a 5.2.13 y 4.2 anterior a 4.2.30. Las solicitudes ASGI con un encabezado ’Content-Length’ faltante o subestimado podrían eludir el límite de ’DATA_UPLOAD_MAX_MEMORY_SIZE’ al leer ’HttpRequest.body’, permitiendo a atacantes remotos cargar un cuerpo de solicitud ilimitado en la memoria. Las series de Django anteriores y no compatibles (como 5.0.x, 4.1.x y 3.2.x) no fueron evaluadas y también podrían estar afectadas. Django desea agradecer a Superior por reportar este problema.
