What is CVE-2026-33034?

A vulnerability in the Django framework could allow remote attackers to bypass the DATA_UPLOAD_MAX_MEMORY_SIZE limit due to improperly handled ASGI requests with an absent or incorrect Content-Length header. This oversight may lead to unbounded memory consumption, presenting a significant risk for applications relying on impacted versions. Django encourages users to update to the latest patched releases to mitigate this issue.
