    CVE-2024-21668

    Published: 9 Jan 2024Last Modified: 28 Oct 2026

    Summary: Insertion of Sensitive Information into Log File in react-native-mmkv

    Details: react-native-mmkv is a library that allows easy use of MMKV inside React Native applications. Before version 2.11.0, the react-native-mmkv logged the optional encryption key for the MMKV database into the Android system log. The key can be obtained by anyone with access to the Android Debugging Bridge (ADB) if it is enabled in the phone settings. This bug is not present on iOS devices. By logging the encryption secret to the system logs, attackers can trivially recover the secret by enabling ADB and undermining an app's thread model. This issue has been patched in version 2.11.0.
