The systems of Sabre Hospitality Solutions (Sabre), a service provider used by Trump Hotels, were the site of this event that suffered from a data breach. On June 5, 2017, Sabre reported that a third party had gained access to account credentials, giving them access to payment card data and particular reservation details for certain of our hotel bookings made through Sabre's CRS.

On July 14, 2017, the California Office of the Attorney General disclosed a data breach affecting Two Roads Hospitality LLC, stemming from unauthorized access to Sabre Hospitality Solutions—a third-party reservation and payment processing system. The breach, which began on August 10, 2016, and persisted until March 9, 2017, involved the compromise of payment card and reservation information of an undisclosed number of individuals. While the exact scope of the exposed data (e.g., names, card numbers, or reservation details) was not specified, the incident highlighted vulnerabilities in third-party vendor systems handling sensitive customer financial data. The prolonged exposure period increased the risk of fraudulent transactions or misuse of payment details. The breach underscored the critical need for robust monitoring and access controls within hospitality industry supply chains, where third-party providers often manage high volumes of transactional and personal data. No ransomware or direct operational disruption was reported, but the incident posed significant reputational and financial risks for both Two Roads Hospitality and its affected customers.
