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.
-
Check installed Chrome versionOpen Chrome, click the three-dot menu > Help > About Google Chrome, or navigate to chrome://settings/helpAffected if The version shown is earlier than 150.0.7871.46
-
Confirm version from command lineOn Windows, run 'chrome --version' in command prompt; on macOS, run '/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version' in Terminal; on Linux, run 'google-chrome --version' or 'chromium --version'Affected if The reported version is earlier than 150.0.7871.46
-
Identify Chrome distribution typeCheck if using Google Chrome or a Chromium-based browser (Edge, Brave, Opera, etc.) by looking at the browser name in the title bar or About menuAffected if The browser is Google Chrome and version is below 150.0.7871.46 (Chromium-based browsers may have different version numbers and patch timelines)
You are affected if running Google Chrome version 150.0.7871.46 or earlier on any platform, as the vulnerability triggers when visiting a crafted HTML page that exploits the race condition in the DataTransfer API.
