Remote crafted page needs no auth (PR:N) but requires the victim to open it (UI:R); browser-scoped privilege escalation yields high C/I/A with unchanged scope, though vendor rates it Medium.
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.

Insufficient policy enforcement in USB in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to perform privilege escalation via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Privilege escalation in Google Chrome's USB subsystem prior to 151.0.7922.72 allows a remote attacker who lures a victim to a crafted HTML page to escalate privileges within the browser through insufficient policy enforcement. Google rates the Chromium security severity as Medium, though the associated CVSS 3.1 score of 8.8 reflects high confidentiality, integrity, and availability impact contingent on user interaction. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively load an attacker-controlled crafted HTML page in a vulnerable Chrome build (before 151.0.7922.72), and the flaw specifically involves Chrome's USB policy-enforcement path (WebUSB device-access handling). … 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:H/I:H/A:H, base 8.8) indicates a network-reachable, low-complexity, unauthenticated attack that requires user interaction - consistent with the description's 'crafted HTML page' delivery. … 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 the insufficient USB policy enforcement and lures a victim into visiting it via phishing or a compromised/malvertising site. When the victim opens the page, the crafted content triggers the privilege-escalation flaw in Chrome's USB handling to gain capabilities beyond the intended web-origin sandbox. … |
| Remediation | Vendor-released patch: 151.0.7922.72 - upgrade Google Chrome to 151.0.7922.72 or later via the Stable channel update (https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html); Chrome's built-in auto-update will apply this after a browser restart, so instruct users to relaunch and verify the version under chrome://settings/help. … Detailed patch versions, workarounds, and compensating controls in full report. |
