CVE-2026-6313
Insufficient policy enforcement in CORS in Google Chrome prior to 147.0.7727.101 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
