Cross-Site Scripting Flaw in Mozilla Bleach by Mozilla

CVE-2020-6802

What is CVE-2020-6802?

A vulnerability in Mozilla Bleach prior to version 3.11 allows for mutation-based Cross-Site Scripting (XSS) attacks. This flaw occurs when users invoke the bleach.clean function with the 'noscript' tag and include a raw tag in their list of allowed tags. Such an improper sanitization can lead to the execution of malicious scripts when rendered in a web application, potentially compromising user security and data integrity. Developers are advised to update to the latest version to mitigate this risk.
