Insufficient policy enforcement in WebUSB in Google Chrome prior to 146.0.7680.178 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Information disclosure in Google Chrome's WebUSB implementation prior to version 146.0.7680.178 allows remote attackers to extract sensitive data from process memory by delivering a crafted HTML page, exploiting insufficient policy enforcement in the WebUSB API. The vulnerability affects all Chrome versions before 146.0.7680.178 across all platforms. No public exploit code or active exploitation has been confirmed at the time of this analysis.
Technical ContextAI
WebUSB is a web standard that enables web pages to access USB devices with user permission, implemented in Chromium-based browsers including Google Chrome. The vulnerability stems from insufficient policy enforcement within the WebUSB implementation, allowing a malicious webpage to bypass intended security boundaries and read sensitive information from the browser process memory. This represents a logic flaw in the access control mechanism governing how web content interacts with USB-related APIs and process memory. The affected product is identified by CPE a:google:chrome across all versions prior to 146.0.7680.178.
RemediationAI
Vendor-released patch: Google Chrome 146.0.7680.178 or later. Users should immediately update Chrome to the patched version through the built-in update mechanism (Settings > About Chrome, or manual download from https://www.google.com/chrome). For enterprise deployments, administrators should deploy Chrome 146.0.7680.178 or newer through their standard update channels. No workarounds exist for unpatched versions; updating is the only remediation. Full details are available in the Chrome stable channel release notes at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_31.html and the Chromium issue tracker at https://issues.chromium.org/issues/489711638.
