The Times has revealed that Labour exposed the names of people who had donated to the party via an online tool. The party denies this represented a security flaw or that a reportable data breach had occurred. It also believes that only a small number of full names were exposed. The details could be found via an RSS web feed generated by the sites code, which most browsers provide a way to inspect. In most cases the data included donors first names, the amount they contributed and the time they made the donation.”]
