Carnival Cruise Line has acknowledged a significant cybersecurity incident that exposed the personal data of close to six million of its passengers. The company confirmed the breach publicly in early June 2026, alerting affected customers to the situation.
Among the compromised information are sensitive details, including passport data, which raises privacy concerns for those impacted. Carnival has advised travelers who have sailed with the line to remain vigilant and monitor their personal information for any signs of misuse, while also recommending precautionary measures.
