Insufficient data validation in CORS in Google Chrome prior to 76.0.3809.87 allowed an attacker who convinced a user to install a malicious extension to bypass content security policy via a crafted Chrome Extension.
Does this matter?
Lower severity and a low EPSS score (0.46%). Track it; it rarely justifies an emergency change on its own.
