    Operator Precedence Logic Error

    dompurify is a DOM-only XSS sanitizer for HTML, MathML and SVG.

    Affected versions of this package are vulnerable to Operator Precedence Logic Error in the form of short-circuit evaluation that gives precedence to ADD_TAGS over FORBID_TAGS in _sanitizeElements(). In an application where ADD_TAGS is used as a function (via EXTRA_ELEMENT_HANDLING.tagCheck) and FORBID_TAGS is in use, an attacker can cause forbidden tags to be allowed.

    How to fix Operator Precedence Logic Error?

    Upgrade dompurify to version 3.4.0 or higher.
