DescriptionCVE.org

Incorrect security UI in Downloads in Google Chrome prior to 147.0.7727.55 allowed a remote attacker who convinced a user to engage in specific UI gestures to perform UI spoofing via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

UI spoofing in Google Chrome's Downloads interface prior to version 147.0.7727.55 allows remote attackers to deceive users into performing unintended actions via crafted HTML pages exploiting incorrect security UI rendering. The vulnerability requires user interaction with specific UI gestures on a malicious webpage, resulting in limited integrity impact through visual deception rather than code execution or data exfiltration. Although marked as low severity by Chromium and carrying minimal exploitation probability (EPSS 0.03%), the attack surface is broad given Chrome's prevalence as a target for social engineering.

Technical ContextAI

This vulnerability resides in Chrome's Downloads UI security layer, specifically in the visual presentation and interaction handling of download-related interface elements. CWE-451 (User Interface (UI) Misrepresentation of Critical Information) classifies the root cause: the browser fails to correctly render or distinguish critical security-related UI elements, allowing attackers to craft HTML content that visually mimics or obscures legitimate download prompts or warnings. The affected component handles the display of download notifications and permission requests, which are rendered via Chromium's UI framework. When a user visits a malicious page and performs specific gestures (likely clicks, hovers, or other interactions), the crafted HTML exploits the rendering flaw to display spoofed UI elements that convince the user the action is legitimate or originates from the browser itself rather than the website.

RemediationAI

Update Google Chrome to version 147.0.7727.55 or later, which includes the fix for the incorrect Downloads UI security rendering. Chrome's auto-update mechanism will deploy this version to most users automatically; users can manually verify their current version via Settings > About Chrome, which will prompt an immediate update check. No workarounds are available for unpatched versions; the vulnerability requires a browser update to resolve. For organizational deployments, administrators should ensure Chrome is configured to auto-update or deploy version 147.0.7727.55+ via enterprise management tools.
