Fiserv and Cencap Federal Credit Union Reach Tentative Settlement in Payment Data Security Lawsuit On March 24, 2026, Fiserv Solutions LLC and Cencap Federal Credit Union tentatively settled a federal lawsuit in the U.S. District Court for the District of Connecticut. The case alleged that Fiserv, a payment processor and fintech provider, operated an online banking platform with critical security vulnerabilities. The lawsuit accused the companies of failing to adequately protect sensitive payment data, though specific details of the alleged flaws remain undisclosed. The settlement, if finalized, would resolve claims stemming from the security concerns without further litigation. The case highlights ongoing scrutiny of financial technology providers over data protection practices, particularly as cyber threats targeting payment systems continue to rise. No further terms of the settlement have been publicly released.

Fiserv, Inc.'s web platform exposed personal and financial details of countless customers across hundreds of bank Web sites. Customer’s email address, phone number and full bank account number was accessible and editable. A cyber criminal could abuse this access to enumerate all other accounts with activity alerts on file, and to add or delete phone numbers or email addresses to receive alerts about account transactions.
