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 confidenceThis vulnerability in McAfee Security: Antivirus VPN for Android versions before 8.3.0 involves improper validation of deep links (URI schemes that trigger specific app actions). An attacker could craft malicious deep links to force the app to open arbitrary URLs, potentially enabling phishing attacks, navigation to malicious content, or exploitation of other URL-handling vulnerabilities within the app context.

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 McAfee Security: Antivirus VPN is installedOn the Android device, go to Settings > Apps and search for 'McAfee Security: Antivirus VPN', or use ADB command: adb shell pm list packages | grep mcafeeAffected if The app is not found in the device's app list, the user is not affected by this specific vulnerability
-
Check the installed version of the appIn Settings > Apps > McAfee Security: Antivirus VPN, view the 'Version' or 'App info' section, or use ADB: adb shell dumpsys package com.mcafee.security.vpn (or com.mcafee.security - use the correct package name found in step 1) | grep versionNameAffected if Unable to retrieve a version number means the app may not be properly installed or is a different McAfee product
-
Compare your version against the affected rangeTake the installed version number from step 2 and compare it to version 8.3.0 - any version lower than 8.3.0 is affected (for example: 8.2.5, 8.2.0, 8.1.2, etc.)Affected if The installed version is any version before 8.3.0, for example 8.2.x, 8.1.x, or earlier major versions - these versions have the improper deep link validation vulnerability
You are affected if McAfee Security: Antivirus VPN for Android is installed and its version number is lower than 8.3.0.

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.
dbcve · scopedUpdate to McAfee Security: Antivirus VPN for Android version 8.3.0 or later. If unable to update immediately, warn users not to click untrusted deep links and consider disabling deep link handling until the patch can be applied.
8.3.0
- Open Google Play Store on the Android device
- Search for 'McAfee Security: Antivirus VPN'
