Summary
DOMPurify is a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG. It has been discovered that malicious HTML using special nesting techniques can bypass the depth checking added to DOMPurify in recent releases. It was also possible to use Prototype Pollution to weaken the depth check. This renders dompurify unable to avoid cross site scripting (XSS) attacks. This issue has been addressed in versions 2.5.4 and 3.1.3 of DOMPurify. All users are advised to upgrade. There are no known workarounds for this vulnerability.

Se ha descubierto que el HTML malicioso que utiliza t\u00e9cnicas de anidaci\u00f3n especiales puede eludir la comprobaci\u00f3n de profundidad agregada a DOMPurify en versiones recientes. Tambi\u00e9n fue posible utilizar Prototype Pollution para debilitar la comprobaci\u00f3n de profundidad. Esto hace que dompurify no pueda evitar los ataques de cross site scripting (XSS). Este problema se ha solucionado en las versiones 2.5.4 y 3.1.3 de DOMPurify. Se recomienda a todos los usuarios que actualicen. No existen workarounds para esta vulnerabilidad."
