Wallet-address disclosure via origin-unchecked JavaScript interface

Published Mar 7, 2026 · Updated Mar 7, 2026

Information disclosure in Freedom Factory dGEN1 20260221 allows remote attackers to read a wallet address through malicious WebView content. MainActivity globally registers AndroidEthereum with addJavascriptInterface, and getAddress returns the Ethereum wallet address without checking the loaded origin or requesting consent. Exploitation requires the user to open an attacker-controlled website or FakeApp in the PWA emulator; no private-key exposure or transaction signing was observed.
