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.

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.
-
Verify Google Chrome is installedOpen Chrome and navigate to chrome://settings/help, or run 'google-chrome --version' or 'chrome --version' in terminalAffected if Google Chrome is not installed - not affected
-
Determine installed Chrome versionOn chrome://settings/help page, note the version number displayed under 'Google Chrome'Affected if Version is blank or cannot be determined - status unknown
-
Compare version to affected rangeCompare the installed version number to 149.0.7827.53 using semantic version comparisonAffected if Installed version is less than 149.0.7827.53 - potentially affected
-
Check if Cast feature is enabledOpen Chrome, click the three-dot menu, look for Cast icon in toolbar or check chrome://flags for 'Cast' settingsAffected if Cast is disabled or not present - lower likelihood of exploitability but version still vulnerable
User is affected if Google Chrome version is below 149.0.7827.53 and the Cast feature is present and enabled on the system
