CVE-2025-61482
📋 TL;DR
This vulnerability allows local attackers with root access on Android devices to bypass two-factor authentication in privacyIDEA Authenticator. By intercepting cryptographic operations, attackers can extract plaintext OTP secrets and generate valid one-time passwords. This affects users of privacyIDEA Authenticator v4.3.0 on Android devices where an attacker gains root access.
