Network-delivered via crafted page, no privileges required, but user must interact with spoofed UI; integrity-only impact as attacker manipulates perceived interface, not underlying data.
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 prior to 151.0.7922.72 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
UI spoofing in Google Chrome's WebAppInstalls component (all versions prior to 151.0.7922.72) allows a remote attacker to misrepresent critical interface elements through a crafted HTML page, deceiving users into interacting with fraudulent Chrome UI. The flaw stems from inappropriate implementation in the Progressive Web App installation flow, rated CVSS 6.5 with high integrity impact reflecting the attacker's ability to manipulate perceived interface state. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim running Google Chrome prior to 151.0.7922.72 to visit an attacker-controlled webpage and actively interact with the spoofed UI element presented during the WebAppInstalls flow (confirmed by UI:R in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N presents a nuanced risk profile: while attack complexity is low and no authentication is required, exploitation is gated on active user interaction (UI:R), which materially reduces mass-exploitation viability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page that abuses Chrome's WebAppInstalls implementation to render a spoofed PWA installation prompt indistinguishable from a legitimate Chrome UI dialog. A victim browsing to the page and interacting with the fake prompt - for example, clicking an install button - could be manipulated into installing a malicious web application or authorizing an action under a false security context. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, the vendor-released patch confirmed by the Chrome Releases blog at http://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
