SCA: security update for serialize-javascript (GHSA-h9rv-jmmf-4pgx)

medium Tenable Self-Hosted Container Security Plugin ID 422939

Description

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

 - The serialize-javascript npm package before version 2.1.1 is vulnerable to Cross-site Scripting (XSS). It
 does not properly mitigate against unsafe characters in serialized regular expressions. This vulnerability
 is not affected on Node.js environment since Node.js's implementation of RegExp.prototype.toString()
 backslash-escapes all forward slashes in regular expressions. If serialized data of regular expression
 objects are used in an environment other than Node.js, it is affected by this vulnerability.
 (CVE-2019-16769)
