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. Versions prior to 0.0.26 have a denial of service vulnerability when parsing crafted multipart/form-data requests with large preamble or epilogue sections. Upgrade to version 0.0.26 or later, which skips ahead to the next boundary candidate when processing leading CR/LF data and immediately discards epilogue data after the closing boundary.
