SCA: security update for python-multipart (GHSA-6jv3-5f52-599m)

low Tenable Cloud Security Plugin ID 443224

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 0.0.30, QuerystringParser treated ;
as a field separator in application/x-www-form-urlencoded bodies, in addition to &. The WHATWG URL
standard, modern browsers, and Python's urllib.parse (since the CVE-2021-23336 fix) treat only & as a
separator. This creates a parser differential: the same bytes are tokenized into different fields than a
WHATWG compliant intermediary would produce, allowing an attacker to smuggle extra form fields past an
upstream body inspecting component. This vulnerability is fixed in 0.0.30. (CVE-2026-53538)

Solution

Update the python-multipart library and its related packages to version 0.0.30 or later.
