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 Google Chrome version
    Open chrome://version in the address bar, or run 'google-chrome --version' from terminal, or check in Settings > About Chrome
    Affected if Version is lower than 120.0.6099.62
  2. Check Chrome package version on Debian
    Run 'dpkg -l | grep google-chrome' or 'apt show google-chrome-stable'
    Affected if Package version is lower than 120.0.6099.62-1
  3. Check Chrome package version on Fedora
    Run 'rpm -qa | grep google-chrome' or 'dnf info google-chrome-stable'
    Affected if Package version is lower than 120.0.6099.62-1
  4. Verify Side Panel Search feature accessibility
    Open Chrome and check if the Side Panel (right-side panel icon) with Search is visible or has been used - the vulnerability triggers through specific UI interactions with this feature
    Affected if Side Panel Search feature is present and user interacts with it on a vulnerable version

You are affected if you are running any Google Chrome version or package below 120.0.6099.62 and the Side Panel Search feature is accessible to users in your environment.
