NVD Description

Note: Versions mentioned in the description apply only to the upstream python313-python-multipart package and not the python313-python-multipart package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.27, python-multipart has a denial of service vulnerability in multipart part header parsing. When parsing multipart/form-data, MultipartParser previously had no limit on the number of part headers or the size of an individual part header. An attacker could send a request with either many repeated headers without terminating the header block or a single very large header value, causing excessive CPU work before request rejection or completion. This vulnerability is fixed in 0.0.27.
