Las versiones 10.25.7 e inferiores son vulnerables a XSS debido a una falla en la l\u00f3gica del filtro strip_html. El filtro strip_html est\u00e1 dise\u00f1ado para eliminar etiquetas HTML de una cadena antes de la renderizaci\u00f3n, y es ampliamente utilizado como un saneador de XSS. La implementaci\u00f3n utiliza una expresi\u00f3n regular (regex) cuya rama comod\u00edn (<.* [c\u00f3digo_PHP_PoC] ) no coincide con los terminadores de l\u00ednea, por lo que cualquier etiqueta HTML que contenga un car\u00e1cter \\n o \\r pasa sin modificar. Un atacante que puede colocar un salto de l\u00ednea dentro de una etiqueta (p. ej., <img\\nsrc=x\\nonerror=alert(1)>) elude completamente la sanitizaci\u00f3n, ya que los navegadores tratan los saltos de l\u00ednea como espacios en blanco dentro de una etiqueta y ejecutan el gestor onerror/onload/etc. resultante. La explotaci\u00f3n es posible para aplicaciones que tanto renderizan cadenas controladas por el atacante a trav\u00e9s de {{ x | strip_html }} para defenderse contra la inyecci\u00f3n HTML como no escapan por separado esa salida HTML (comportamiento predeterminado - outputEscape no est\u00e1 configurado por defecto).
