Credit card disclosure via brute-force autofill guessing
Published Jun 7, 2022 · Updated Aug 3, 2024
Information disclosure in Samsung Internet before 17.0.1.69 allows physically proximate attackers to guess stored credit card numbers. The credit-card autofill algorithm accepts repeated guesses in a way that reveals whether a candidate number matches stored payment data. Exploitation requires physical access, low privileges, and user interaction, and exposes card numbers without altering data or interrupting service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
