MEDIUM 5.4EPSS 0.79%

Does this matter?

Lower severity and a low EPSS score (0.79%). Track it; it rarely justifies an emergency change on its own.

Description

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.
