Background
The parse-url package is an npm package that provides functionality for parsing and manipulating URLs. It is commonly used in web development projects to handle URL-related operations. However, versions prior to 7.0.0 of the parse-url package are vulnerable to a Cross-Site Scripting (XSS) attack.
Vulnerability Detail
The vulnerability in parse-url allows for stored Cross-Site Scripting (XSS) attacks. This means that an attacker can inject malicious code into the application, which will be executed when a user interacts with the affected page. The XSS vulnerability in parse-url can have various ramifications, including the theft of sensitive user information, session hijacking, defacement of web pages, and the potential for further attacks.
How To Fix
Latest published version: 11.1.0 as of 22 Oct 2026
npm install parse-url@11.1.0Upgrading to it may include breaking changes; the version below is the minimum fixed release for this vulnerability.

Workaround
If updating the parse-url package is not immediately feasible, developers can implement input validation and output encoding to prevent the execution of malicious code. It is crucial to sanitize user input and encode any dynamic content displayed on web pages to mitigate the risk of XSS attacks. Here is an example of input validation and output encoding in JavaScript:
// Input validation
const userInput = document.getElementById('userInput').value;
const sanitizedInput = userInput.replace(/<[^>]*>/g, '');
// Output encoding
const dynamicContent = '<script>alert('XSS');</script>';
const encodedContent = document.createElement('div');
encodedContent.innerText = dynamicContent;
// Display encoded content
document.getElementById('output').appendChild(encodedContent);
Conclusion
The parse-url package prior to version 7.0.0 is vulnerable to a Cross-Site Scripting (XSS) attack. This can lead to the execution of malicious code on web pages, potentially resulting in the theft of sensitive information and other security risks. It is crucial to update the parse-url package to version 6.0.1 or later and implement input validation and output encoding to mitigate the vulnerability.
