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 Chrome versionNavigate to chrome://settings/help or click Help > About Google Chrome to view the installed version numberAffected if The displayed version is lower than 149.0.7827.53
-
Review installed extensionsNavigate to chrome://extensions/ and review the list of installed extensionsAffected if Any extension is installed that was not obtained from the trusted Chrome Web Store, or any extension of unknown or untrusted origin
-
Check extension installation policyInspect group policy settings for extension management: on Windows run gpedit.msc and navigate to Computer Configuration > Administrative Templates > Google Chrome > Extensions, or check for enterprise policies controlling extension installationAffected if No organizational policies are in place to restrict extension installation sources
A user is affected if their Chrome version is below 149.0.7827.53 AND they have installed a malicious or untrusted extension, as the vulnerability requires a crafted extension to be present to access the sensitive DevTools process memory.
