By loading a specially crafted web page, the attacker can cause Chrome to display a deceptive URL that does not match the actual page being viewed. This manipulation can trick users into believing they are interacting with a trusted site, potentially leading to phishing and credential theft.

The vulnerability is not listed in the CISA KEV catalog, implying it has not yet been actively used in the wild. Exploitation requires a remote attack that first gains control of a renderer process, which typically means delivering a malicious website or taking advantage of another local compromise. Given these prerequisites, the likelihood of successful exploitation is low but non\u2011zero, and administrators should prioritize patching when possible."}}}}, "created": "2026-04-09T08:17:22.570776+00:00", "updated": "2026-04-15T16:15:11.922985+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
