SCA: security update for fast-xml-parser (GHSA-6w63-h3fj-q4vw)

high Tenable Cloud Security Plugin ID 411664

Description

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

 - fast-xml-parser is an open source, pure javascript xml parser. fast-xml-parser allows special characters
 in entity names, which are not escaped or sanitized. Since the entity name is used for creating a regex
 for searching and replacing entities in the XML body, an attacker can abuse it for denial of service (DoS)
 attacks. By crafting an entity name that results in an intentionally bad performing regex and utilizing it
 in the entity replacement step of the parser, this can cause the parser to stall for an indefinite amount
 of time. This problem has been resolved in v4.2.4. Users are advised to upgrade. Users unable to upgrade
 should avoid using DOCTYPE parsing by setting the `processEntities: false` option. (CVE-2023-34104)

Solution

Update the fast-xml-parser library and its related packages to version 4.2.4 or later.
