CVE-2025-61482
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper handling of OTP/TOTP/HOTP values in NetKnights GmbH privacyIDEA Authenticator v.4.3.0 on Android allows local attackers with root access to bypass two factor authentication. By hooking into app crypto routines and intercepting decryption paths, attacker can recover plaintext secrets, enabling generation of valid one-time passwords, and bypassing authentication for enrolled accounts.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe privacyIDEA Authenticator Android app v4.3.0 improperly handles OTP/TOTP/HOTP secrets during decryption operations. A local attacker with root access can hook into the app's crypto routines and intercept decryption paths to recover plaintext secrets, enabling generation of valid one-time passwords and bypassing two-factor authentication for enrolled accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if privacyIDEA Authenticator is installedOpen Android Settings > Apps and search for 'privacyIDEA Authenticator', or use a mobile device management (MDM) inventory to check for this app on managed devicesAffected if The app is present on the device
-
Check the installed app versionIn Android Settings > Apps > privacyIDEA Authenticator, view the version information under 'App info' or 'Version'; compare the version number to 4.3.0Affected if The installed version is 4.3.0
-
Determine if the device has root accessUse an MDM tool or a root detection app to check if the device is rooted; alternatively, verify if the device bootloader is unlocked or if superuser binaries are presentAffected if The device has root access enabled
-
Check for enrolled OTP tokensOpen the privacyIDEA Authenticator app and review the list of enrolled accounts or tokens to see if any TOTP/HOTP secrets are storedAffected if One or more OTP accounts or tokens are enrolled in the app
A device is affected if the privacyIDEA Authenticator app version 4.3.0 is installed, the device has root access, and the app contains enrolled OTP tokens.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to a patched version when available. In the interim, consider device screening, MDM policies restricting rooted devices for high-security accounts, and monitor for unusual OTP token enrollment requests.
