Product timeline
Tangem released iOS 5.19.1 and Android 5.19.2 to fix mobile-app log exposure
Product: Tangem App
Tangem's official security changelog records a December 27, 2024 security/bugfix release that fixed the mobile-app logging bug for the same seed-phrase plus in-app-support condition.
Tangem App logging bug could include private-key material in diagnostic logs
Product: Tangem App
Tangem disclosed that when a wallet was activated with a generated or imported seed phrase, a bug in the mobile app's NFC logging mechanism could write the private key into app logs. Potential exposure required the user to also contact Tangem support through the app within seven days, allowing those logs to be included with the support interaction.
