MLB class action lawsuit overview:

Who: A fan has filed a class action lawsuit against MLB Advanced Media.
Why: The plaintiff claims the company failed to protect digital tickets purchased through the MLB mobile ticketing app.
Where: The MLB app class action lawsuit was filed in New York federal court.

A new class action lawsuit alleges that MLB Advanced Media failed to adequately protect digital tickets purchased through the MLB mobile ticketing app, resulting in unauthorized access and theft of tickets during the 2025 MLB season.

Plaintiff James Lanham argues in the MLB app class action lawsuit that the MLB mobile ticketing app, which serves as a digital wallet for baseball tickets, was breached by cybercriminals, leading to the disappearance or theft of tickets from fans’ accounts.

Lanham claims that MLB failed to publicly disclose the data breach or notify affected consumers, leaving them unaware of the potential compromise of their personal identifying information and unable to take protective measures.

Lanham was reportedly forced to purchase new tickets and missed part of a Chicago Cubs game after his original tickets disappeared from his MLB mobile ticketing app account.

The MLB app class action lawsuit alleges that MLB’s response to the data breach has been inadequate, with no public acknowledgment of the incidents or compensation offered to affected fans.

MLB allegedly failed to implement two-factor authentication

Lanham claims that MLB’s failure to implement industry-standard security measures, such as two-factor authentication, contributed to the breach.

The MLB app class action lawsuit alleges that the MLB mobile ticketing app lacks sufficient data security protocols, making it vulnerable to cyberattacks.

Lanham argues that MLB’s failure to protect fans’ digital tickets and personal information constitutes negligence, breach of implied contract and unjust enrichment.

The MLB app class action lawsuit seeks to represent a class of individuals and entities in the United States who had tickets for the 2025 MLB season that were subject to unauthorized transfer or theft due to the data breach.

Meanwhile, the major league baseball team Washington Nationals has agreed to a $3 million settlement to resolve claims that it discriminated against older baseball fans by denying them access to a “Millennial” ticket discount.
