| Doc Text: |
A flaw was found in DOMPurify, a DOM-only cross-site scripting sanitizer. A remote attacker could exploit an inconsistency in how forbidden tags and attributes are handled when function-based tag additions are used. This allows malicious HTML, MathML, or SVG elements to bypass sanitization and execute arbitrary code in the user's browser, leading to Cross-Site Scripting (XSS).
