CVE-2019-16772: Serialize-To-Js Project Serialize-To-Js

Medium severity, CVSS 6.1. EPSS: 0.6% chance of exploitation in the next 30 days.

The serialize-to-js NPM package before version 3.0.1 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.

Affected products

• Serialize-To-Js Project Serialize-To-Js: before 3.0.1 (fixed in 3.0.1)
