Vulnerability Details

A Denial of Service (DoS) vulnerability was discovered in starlette prior to 0.25.0. The MultipartParser using the package python-multipart accepts an unlimited number of multipart parts (form fields or files). Processing too many parts results in high CPU usage and high memory usage, eventually leading to an OOM process kill. This can be triggered by sending too many small form fields with no content, or too many empty files.
