Mitigation Strategies

To mitigate this vulnerability, it is recommended to configure file upload size limits at the web server level rather than relying solely on Django's FILE_UPLOAD_MAX_MEMORY_SIZE setting.

Ensure that your Django version is updated to 6.0.5 or later, or 5.2.14 or later, as these versions address the issue.

Executive Summary

This vulnerability occurs in Django versions 6.0 before 6.0.5 and 5.2 before 5.2.14. It involves ASGI requests that have a missing or understated Content-Length header, which can bypass the FILE_UPLOAD_MAX_MEMORY_SIZE limit.

Because of this bypass, large files can be loaded into memory without restriction, potentially causing service degradation.

Django recommends configuring upload size limits at the web server level rather than relying solely on the FILE_UPLOAD_MAX_MEMORY_SIZE setting.
