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://version in the Chrome address bar or go to chrome://settings/help to view the current version numberAffected if The displayed version is below 148.0.7778.216 (or 148.0.7778.215) and thus falls within the vulnerable range
-
Verify V8 engine is presentThis vulnerability exists in the V8 JavaScript engine which is included by default in all Chrome installations - no additional verification neededAffected if Chrome is running and V8 is present, which is the default configuration for all Chrome installations
-
Confirm extension installation capabilityThe attack requires a malicious extension to be installed.
