CVE-2026-124599
Received Received - Intake

Hard-Coded RSA Keys in Android Application

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: GV

Description
The RSA cryptographic key material, including a private key and public key, is embedded within the application package. Because Android applications can be extracted and reverse engineered, storing private cryptographic keys directly inside the client application may allow an attacker to recover the keys and potentially use them to impersonate the application, decrypt protected data, or generate unauthorized cryptographic operations.

Executive Summary

This vulnerability involves private cryptographic keys being embedded directly within an Android application package. Since Android apps can be reverse engineered, attackers can extract these keys and use them to impersonate the app, decrypt sensitive data, or perform unauthorized cryptographic operations.

Detection Guidance

This vulnerability involves private keys embedded in Android applications, which can be detected by analyzing APK files for hardcoded cryptographic keys. Use tools like apktool to decompile the APK and search for key files or strings containing 'private key' or 'RSA' in the code. Check for files like .pem, .key, or .keystore in the extracted resources.

Impact Analysis

If you use an affected application, attackers could impersonate the app to access your data, decrypt protected information, or perform actions on your behalf. This could lead to unauthorized access to personal or sensitive data stored or transmitted by the app.

Compliance Impact

This vulnerability could violate compliance requirements under GDPR and HIPAA by exposing personal or health data due to weak cryptographic protection. Organizations may face penalties for failing to protect sensitive data adequately.

Mitigation Strategies

Remove private cryptographic keys from the application package and store them securely on a server. Use secure key management practices like Android Keystore or hardware security modules. Avoid embedding keys in client-side code.
