Executive Summary

This vulnerability exists in the sanitize-html library prior to version 1.0.3, specifically in the function 'naughtyHref' that sanitizes the 'href' attribute in anchor (<a>) tags. The function fails to properly validate the URL scheme in the 'href' attribute because it only matches lowercase letters and does not decode HTML entities or handle whitespace characters. Attackers can exploit this by encoding 'javascript:' URLs using uppercase letters, whitespace, or HTML character references, allowing malicious JavaScript code to execute when users click on these sanitized links. This is a Cross-site Scripting (XSS) vulnerability. [1, 3]

Impact Analysis

This vulnerability can lead to Cross-site Scripting (XSS) attacks, where an attacker injects malicious JavaScript code into web pages viewed by other users. If exploited, it can allow attackers to execute arbitrary scripts in the context of the affected website, potentially stealing user data, hijacking user sessions, or performing actions on behalf of the user without their consent. This can compromise the security and integrity of your web application and its users. [1, 3]
