The dialog\u2019s security UI is incorrectly displayed, enabling the attacker to spoof the interface and potentially trick users into installing malicious or deceptive web applications.

Due to the low EPSS, widespread exploitation is unlikely, but the user deception potential remains a concern for phishing or malicious web application distribution."}}}}, "created": "2026-03-12T09:55:17.139616+00:00", "updated": "2026-04-16T03:00:09.182125+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
