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

Published Apr 7, 2026
·
Updated

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 DATAUPLOADMAXMEMORYSIZE 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.
