CVE-2026-33034
Django vulnerability analysis and mitigation

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.
