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

In the addLinks function of Android's Linkify.java utility, a vulnerability allows malicious manipulation of clickable links. This could potentially redirect users to malicious URLs or trigger unintended actions, with the 'unusual root cause' suggesting a non-standard flaw in how Linkify processes and converts text to clickable hyperlinks.

MitigationApply available Android security patches for the affected versions (Android 7.0-9) which address this vulnerability in the Framework component.

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 Android OS version
    Go to Settings > About Phone > Android version, or run 'adb shell getprop ro.build.version.release'
    Affected if The version displayed is 7.0, 7.1.1, 7.1.2, 8.0, 8.1, or 9.0
  2. Verify Android security patch level
    Go to Settings > About Phone > Security patch level, or run 'adb shell getprop ro.build.version.security_patch'
    Affected if The security patch level is earlier than the March 2019 patch or not set
  3. Confirm Linkify usage in applications
    Review application source code for imports of android.text.util.Linkify or usage of Linkify.addLinks() API
    Affected if Any application uses Linkify to convert text to clickable hyperlinks on a vulnerable Android version

A user is affected if their Android device runs version 7.0, 7.1.1, 7.1.2, 8.0, 8.1, or 9.0 and uses applications that leverage the Linkify API to create clickable links.
