SCA: security update for schema-inspector (GHSA-f38p-c2gq-4pmr)

high Tenable Self-Hosted Container Security Plugin ID 414220

Description

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

 - Schema-Inspector is an open-source tool to sanitize and validate JS objects (npm package schema-
 inspector). In before version 2.0.0, email address validation is vulnerable to a denial-of-service attack
 where some input (for example
 `a@0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.`) will freeze
 the program or web browser page executing the code. This affects any current schema-inspector users using
 any version to validate email addresses. Users who do not do email validation, and instead do other types
 of validation (like string min or max length, etc), are not affected. Users should upgrade to version
 2.0.0, which uses a regex expression that isn't vulnerable to ReDoS. (CVE-2021-21267)
