Its EPSS score is below 1%, suggesting a low but non-zero probability of exploitation at the time of analysis, and it is not currently listed in CISA's KEV catalog. The likely attack vector involves a remote user tricking a victim into opening a malicious web page that exploits the V8 engine; the exploitation requires the victim to have Chrome installed and to visit the malformed page. Given these conditions, the risk is notable but primarily depends on user interaction and the prevalence of the vulnerability in the installed Chrome version."}}}}, "created": "2026-03-05T09:05:51.588207+00:00", "updated": "2026-04-17T13:15:19.653650+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
