Insufficient policy enforcement in Chromecast in Google Chrome prior to 151.0.7922.72 allowed an attacker on the local network segment to inject scripts or HTML into a privileged page via malicious network traffic.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
