SCA: security update for tornado (GHSA-7cx3-6m66-7c5m)

high Tenable Cloud Security Plugin ID 427714

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. When Tornado's ``multipart/form-
 data`` parser encounters certain errors, it logs a warning but continues trying to parse the remainder of
 the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS
 attack. This DoS is compounded by the fact that the logging subsystem is synchronous. All versions of
 Tornado prior to 6.5.0 are affected. The vulnerable parser is enabled by default. Upgrade to Tornado
 version 6.50 to receive a patch. As a workaround, risk can be mitigated by blocking `Content-Type:
 multipart/form-data` in a proxy. (CVE-2025-47287)
