Kerentanan Improper Validation of Specified Quantity in Input pada fastapiexpert python-multipart. Skor CVSS 3.1 3.7 (Low) menurut github.com.

Deskripsi (NVD)

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.31, parse_form() did not validate the Content-Length header before using it to bound its chunked read of the request body. A negative Content-Length turned the bounded read into a read-until-EOF, so the entire body was loaded into memory in a single read instead of in fixed-size chunks. This vulnerability is fixed in 0.0.31.
