Descriptions
An issue was discovered in Bleach 2.1.x before 2.1.3. Attributes that have URI values weren't properly sanitized if the values contained character entities. Using character entities, it was possible to construct a URI value with a scheme that was not allowed that would slide through unsanitized.
Se ha descubierto un problema en Bleach, en versiones 2.1.x anteriores a la 2.1.3. Los atributos que tienen valores URI no se sanearon correctamente si los valores contenían entidades de caracteres. Mediante el uso de entidades de caracteres, era posible construir un valor de URI con un esquema no permitido que pasaría sin sanearse.
