  3. CVE-2025-15599
DOMPurify 3.1.3 through 3.2.6 and 2.5.3 through 2.5.8 contain a cross-site scripting vulnerability that allows attackers to bypass attribute sanitization by exploiting missing textarea rawtext element validation in the SAFE_FOR_XML regex. Attackers can include closing rawtext tags like </textarea> in attribute values to break out of rawtext contexts and execute JavaScript when sanitized output is placed inside rawtext elements. The 3.x branch was fixed in 3.2.7; the 2.x branch was never patched.

Summary
  • (es) DOMPurify 3.1.3 hasta 3.2.6 y 2.5.3 hasta 2.5.8 contienen una vulnerabilidad de cross-site scripting que permite a los atacantes eludir la sanitización de atributos al explotar la falta de validación del elemento rawtext de textarea en la expresión regular SAFE_FOR_XML. Los atacantes pueden incluir etiquetas de cierre de rawtext como en los valores de los atributos para salir de los contextos de rawtext y ejecutar JavaScript cuando la salida sanitizada se coloca dentro de elementos rawtext. La rama 3.x se corrigió en 3.2.7; la rama 2.x nunca fue parcheada.
