| Doc Text: |
A flaw was found in DOMPurify. This vulnerability allows attackers to bypass application security policies by preserving sensitive attributes on custom elements. These attributes can then be re-injected into web page content, leading to Cross-Site Scripting (XSS) attacks. An attacker could exploit this to execute malicious scripts in a user's browser, potentially leading to information disclosure or unauthorized actions.
