Dompurify · Dompurify · CVE-2026-65913
**Name of the Vulnerable Software and Affected Versions**
DOMPurify versions prior to 3.3.2
**Description**
When operating in USE PROFILES mode, the software is susceptible to prototype pollution. This occurs when attackers pollute `Array.prototype` properties, such as setting `onclick` to true, to bypass attribute filtering. Consequently, the system may accept event handlers as allowlisted attributes, leading to DOM-based Cross-Site Scripting (XSS), where malicious scripts are executed in the browser when sanitized markup is rendered.
**Recommendations**
Update to version 3.3.2 or later.
