The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog, suggesting no widespread active exploitation has been reported. Attackers can exploit the flaw by simply navigating to a malicious site; no additional conditions are needed. The combination of high impact with low exploitability moderates overall risk, but the severity warrants precautionary action."}}}}, "created": "2026-03-12T09:55:25.728881+00:00", "updated": "2026-04-16T03:00:09.185202+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
