CVE-2026-33034

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

State: Published
Severity: 7.5 High
Published: Apr 7, 2026
Updated: Apr 7, 2026
Reserved: Mar 17, 2026

Description

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.
