SCA: security update for html-sanitizer (GHSA-wvhx-q427-fgh3)

medium Tenable Self-Hosted Container Security Plugin ID 420134

Description

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

 - html-sanitizer is an allowlist-based HTML cleaner. If using `keep_typographic_whitespace=False` (which is
 the default), the sanitizer normalizes unicode to the NFKC form at the end. Some unicode characters
 normalize to chevrons; this allows specially crafted HTML to escape sanitization. The problem has been
 fixed in 2.4.2. (CVE-2024-34078)
