high Tenable Cloud Security Plugin ID 441308

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-42561)

Solution

Update the python-multipart library and its related packages to version 0.0.27 or later.
