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 Google Chrome is installedOn Windows, check Program Files/Google/Chrome/Application/chrome.exe version via Properties, or run 'chrome --version' from command line. On Linux, run 'google-chrome --version' or 'chromium --version'. On macOS, run '/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version'Affected if Google Chrome browser is present on the system
-
Determine installed Chrome versionExecute 'google-chrome --version' in terminal or check chrome://help page within the browserAffected if Version number is lower than 112.0.5615.49 (e.g., 112.0.5615.48 or earlier)
-
Confirm Browser History feature accessibilityThe vulnerability requires user interaction with the Browser History component - verify the History page is accessible via chrome://history or by pressing Ctrl+HAffected if History feature is enabled and accessible to the user account
-
Check Linux OS version if applicableOn Fedora systems, run 'cat /etc/fedora-release'. On Debian, run 'cat /etc/debian_version'Affected if Running Fedora 36 or 37, or Debian 11.0, with an unpatched Chrome version
You are affected if Google Chrome (or Chromium) is installed with a version below 112.0.5615.49 and the Browser History feature is accessible on the system.
