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
The Newphoria Reversi application before 1.0.3 for Android and before 1.2 for iOS allows attackers to bypass a URL whitelist protection mechanism and obtain API access via unspecified vectors.

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 Newphoria Reversi mobile application for Android and iOS contained a flawed URL whitelist protection mechanism that could be bypassed by attackers, allowing unauthorized access to backend API endpoints. The vulnerability resided in the application's client-side validation of allowed URLs, which failed to properly restrict API access as intended.

MitigationDevelopers should update to version 1.0.3+ (Android) or 1.2+ (iOS) which contain the fix. The fix requires implementing proper server-side validation of API requests and ensuring the whitelist cannot be bypassed through manipulation of request parameters or URLs.

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. Check installed app version on Android
    Open device Settings > Apps > Reversi and view the Version information, or use adb shell dumpsys package com.newphoria.reversi to retrieve versionName and versionCode
    Affected if The version is 1.0.2 or earlier (versionCode lower than the build corresponding to 1.0.3)
  2. Check installed app version on iOS
    Open Settings > General > About > Reversi to view the Version number, or use idevicediagnostics -u or iTunes to inspect the app's Info.plist for CFBundleShortVersionString
    Affected if The version is 1.1 or earlier (version number lower than 1.2)
  3. Verify client-side URL whitelist validation exists
    For Android, decompile the APK (using apktool) and search for URL whitelist logic in the source code (look for whitelist, allowedURL, validateUrl, or similar patterns). For iOS, analyze the binary or extracted code for similar validation functions.
    Affected if The application contains code that performs client-side validation of URLs against a whitelist array or list
  4. Test whitelist bypass vulnerability
    If client-side URL whitelist validation is present, intercept app traffic using a proxy (Burp Suite, mitmproxy) and attempt to modify request URLs to access API endpoints outside the declared whitelist by using URL manipulation techniques such as path traversal, parameter injection, or subdomain switching
    Affected if API requests to non-whitelisted URLs succeed when they should be blocked, indicating the whitelist can be bypassed

A user is affected if they are running Reversi version 1.0.2 or earlier on Android or version 1.1 or earlier on iOS and the app contains exploitable client-side URL whitelist validation.
