A data leakage incident exposed the national ID numbers of 1,573 candidates for Taiwan's upcoming local elections. The Central Election Commission (CEC) confirmed that the data was accessible from October 16 to October 27, 2026, due to a flaw in their financial disclosure website. Candidates affected include major figures such as Taipei Mayor Chiang Wan-an and his rival Puma Shen. The breach was reported by the Taiwan Go Go political alliance, which stated that the data was automatically transmitted to visitors of the site. The CEC has since taken the website offline for a security patch and is conducting an investigation. Concerns have been raised about the potential for identity theft and scams due to the exposure of sensitive personal information. This incident follows a previous breach in 2022 that compromised 23 million household registration records.
