SCA: security update for tornado (GHSA-qjxf-f2mg-c6mc)

high Tenable Self-Hosted Container Security Plugin ID 438726

Description

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

 - Tornado is a Python web framework and asynchronous networking library. In versions of Tornado prior to
 6.5.5, the only limit on the number of parts in multipart/form-data is the max_body_size setting (default
 100MB). Since parsing occurs synchronously on the main thread, this creates the possibility of denial-of-
 service due to the cost of parsing very large multipart bodies with many parts. This vulnerability is
 fixed in 6.5.5. (CVE-2026-31958)

Solution

Update the tornado library and its related packages to version 6.5.5 or later.
