Description specifies a local attacker delivering a malicious file the user must open, so AV:L and UI:R; UI spoofing is limited integrity impact (I:L), no C or A.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Inappropriate implementation in WebAppInstalls in Google Chrome on Android prior to 150.0.7871.47 allowed a local attacker to perform UI spoofing via a malicious file. (Chromium security severity: Low)
AnalysisAI
UI spoofing in Google Chrome for Android before 150.0.7871.47 lets a local attacker misrepresent browser interface elements through the WebAppInstalls component using a malicious file. The flaw (CWE-451) requires a crafted file to be opened on the device and could deceive users into trusting spoofed content or install prompts. Google rates the Chromium security severity as Low, no public exploit has been identified, and EPSS is negligible at 0.11%.
Technical ContextAI
The vulnerability lies in Chrome's WebAppInstalls feature on Android, the subsystem responsible for handling Progressive Web App / web app installation flows. The root cause is CWE-451 (User Interface Misrepresentation of Critical Information), meaning the browser renders or attributes UI elements - such as install dialogs, origin indicators, or app metadata - in a way that does not accurately reflect the underlying source. By supplying a malicious file that is processed through this install path, an attacker can cause the UI to display misleading information. The affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* on the Android platform specifically; desktop channels are not implicated by the description.
RemediationAI
Vendor-released patch: update Google Chrome for Android to 150.0.7871.47 or later via the Google Play Store or managed enterprise deployment (see the Chrome release advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html). Because the attack requires a malicious file to be opened on the device, an effective compensating control until update is to avoid opening untrusted files in Chrome and to restrict sideloading of files from unknown sources; enforcing managed Chrome auto-updates through Google Play or an MDM removes user-driven update lag. There is no server-side toggle to disable WebAppInstalls independently, so patching remains the primary and cleanest fix; the trade-off of the file-hygiene control is that it depends on user behavior and does not eliminate the underlying spoofing logic.
