Fukuoka Prefecture Application File Left Open for Online Editing, Exposing Personal Data of 183 Corporate Officers

According to Security NEXT, an improperly configured application file on the website for Fukuoka Prefecture's nursing care workplace certification program allowed personal data of 183 corporate officers across 24 organizations to be viewed by third parties ^[1]. Between August 21 and September 17, 2026, a contractor mistakenly configured the file to allow online editing and saving, leaving entered names, dates of birth, genders, and job titles accessible online ^[1]. The prefecture discovered the issue after receiving an inquiry from an applicant, ordered the file removed, and telephoned all 24 affected organizations to explain and apologize ^[1].
