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 · unedited
An incorrect access control issue in Life: Personal Diary, Journal android app 17.5.0 allows a physically proximate attacker to escalate privileges via the fingerprint authentication function.

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 · moderate confidence

The Life: Personal Diary app version 17.5.0 for Android contains an incorrect access control vulnerability in its fingerprint authentication mechanism. A physically proximate attacker can exploit this flaw to bypass authentication and escalate privileges, likely by manipulating the fingerprint verification logic flow.

MitigationUpdate to a patched version of the app when available. Until then, disable fingerprint authentication and use alternative authentication methods.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Life: Personal Diary app version
    Check installed app version via Android Settings > Apps > Life: Personal Diary, or use ADB command: adb shell dumpsys package com.hitbytes.life | grep versionName
    Affected if Installed version is exactly 17.5.0
  2. Confirm fingerprint authentication is enabled
    Open the app, go to Settings > Security/Fingerprint Authentication, and verify if fingerprint unlock is turned ON
    Affected if Fingerprint authentication toggle is enabled in the app settings
  3. Check device biometric enrollment status
    Navigate to Android Settings > Security > Biometrics, or check if device has enrolled fingerprints under Settings > Fingerprints
    Affected if Device has at least one fingerprint enrolled and biometric authentication is available to the app
  4. Test fingerprint authentication behavior
    Lock the app (background it) and attempt to reopen using fingerprint authentication
    Affected if Fingerprint authentication fails to properly validate or allows bypass when fingerprint is presented

User is affected if Life: Personal Diary version 17.5.0 is installed AND fingerprint authentication is enabled and functional on the device.
