high Tenable Self-Hosted Container Security Plugin ID 440678

Description

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

 - lxml is a library for processing XML and HTML in the Python language. Prior to 6.1.0, using either of the
 two parsers in the default configuration (with resolve_entities=True) allows untrusted XML input to read
 local files. Setting the resolve_entities option explicitly to resolve_entities='internal' or
 resolve_entities=False disables the local file access. This vulnerability is fixed in 6.1.0.

Solution

Update the lxml library and its related packages to version 6.1.0 or later.
