  "details" : [ "A flaw was found in DOMPurify, a software library used to clean potentially malicious code from web content, preventing Cross-Site Scripting (XSS) attacks. A remote attacker could exploit a vulnerability related to 'prototype pollution' to bypass DOMPurify's security checks. This allows the attacker to inject harmful code, such as event handlers, into web pages. If successfully exploited, this could lead to the execution of arbitrary code in a user's web browser." ],
