Background
The serialize-to-js package is an npm package used for serializing JavaScript objects into a string representation that can be easily deserialized back into objects. It is commonly used in web applications to transfer data between the client and server. However, versions prior to 3.0.1 are vulnerable to Cross-Site Scripting (XSS) attacks. This vulnerability occurs because the package fails to properly sanitize serialized regular expressions. It is important to note that this vulnerability does not affect Node.js applications.
