A remote attacker can craft a malicious HTML page that, when visited by a user, triggers the Chrome Downloads UI with misleading information, allowing the attacker to spoof the download dialog. As a result, users may be forced to download or interact with unwanted or malicious content. This flaw exploits the weakness categorized as CWE-451.", "risk_and_exploitability": "The CVSS score is 6.5, indicating moderate severity, while the EPSS score is below 1%, suggesting a low probability of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog, further indicating low exploitation activity. The attack vector is remote, requiring the victim to open a crafted HTML page in Chrome on Android. Because it is a UI spoofing flaw, an attacker cannot directly achieve code execution but can potentially lure a user into downloading malicious content, leading to indirect compromise."}}}}, "created": "2026-03-12T09:55:15.238429+00:00", "title": "UI Spoofing via Incorrect Download Security UI in Google Chrome Android", "updated": "2026-03-20T15:36:43.553936+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
