Echo: python-multipart: security update to 0.0.31

low Tenable Self-Hosted Container Security Plugin ID 463753

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 0.0.31, 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.
(CVE-2026-53540)

Solution

Update the python-multipart library and its related packages to version 0.0.31 or later.
