CVE-2026-14034: Google Chrome Auth Bypass Vulnerability

CVE-2026-14034 Overview

CVE-2026-14034 is a navigation restriction bypass in the WebXR component of Google Chrome on Android. Versions prior to 150.0.7871.47 are affected. A remote attacker can leverage a crafted HTML page to bypass navigation restrictions enforced by the browser. Chromium classified the security severity as Low, and the issue is tracked under [CWE-284] Improper Access Control.

Exploitation requires user interaction, such as visiting a malicious page or interacting with a WebXR-enabled site. The vulnerability affects integrity but does not directly expose data or crash the browser process.

Critical Impact
Remote attackers can bypass browser navigation restrictions on Android devices running vulnerable Chrome builds, enabling redirection or context manipulation attacks against WebXR users.

Affected Products

Google Chrome on Android prior to 150.0.7871.47
Google Android platform running affected Chrome builds
WebXR-enabled web sessions in Chromium-based mobile builds sharing the affected code path

Technical Details for CVE-2026-14034

Vulnerability Analysis

The flaw resides in the WebXR implementation shipped with Google Chrome on Android. WebXR is the browser API that exposes virtual and augmented reality device capabilities to web content. The affected code did not correctly enforce Chromium's navigation restriction rules when handling WebXR sessions.

As a result, a crafted HTML page can cause the browser to perform navigation actions that the security model is intended to block. The CWE-284 classification confirms this is an access control failure rather than a memory safety issue. Impact is limited to integrity of the browsing context, with no direct confidentiality or availability effect.

The issue is tracked in the Chromium Issue Tracker Entry and addressed in the Chrome Desktop Update Announcement.

Root Cause

The root cause is an inappropriate implementation within Chrome's WebXR module that fails to consistently apply navigation policy checks. When a WebXR session interacts with page navigation logic, the browser processes requests without applying the origin and navigation boundaries expected under Chromium's security model.

Attack Vector

An attacker hosts a crafted HTML page that invokes WebXR functionality. When a user on an Android device running a vulnerable Chrome build loads the page, the attacker can trigger navigation actions that would normally be blocked. User interaction is required, but no authentication or elevated privileges are needed. Exploitation code is not publicly available and no in-the-wild activity has been reported.

No verified proof-of-concept code has been published. See the linked Chromium issue tracker for further technical detail.

Detection Methods for CVE-2026-14034

Indicators of Compromise

Unexpected navigation events on Android devices originating from pages that invoke WebXR APIs such as navigator.xr.requestSession()
Chrome version strings below 150.0.7871.47 reported by browser fleet inventory tools
Outbound requests to unfamiliar domains immediately following user visits to WebXR-enabled content

Detection Strategies

Inventory installed Chrome versions across managed Android endpoints and flag builds earlier than 150.0.7871.47
Inspect web proxy and DNS logs for redirection chains originating from pages that reference WebXR script APIs
Correlate mobile browser telemetry with reputation feeds to surface suspicious WebXR-hosting domains

Monitoring Recommendations

Enable mobile browser update compliance reporting in enterprise mobility management (EMM) consoles
Alert on Chrome installations that fall behind the current stable channel by more than one release
Monitor for user reports of unexpected page navigation or content substitution on Android Chrome

How to Mitigate CVE-2026-14034

Immediate Actions Required

Update Google Chrome on Android to version 150.0.7871.47 or later through the Google Play Store
Push the updated Chrome build to managed Android devices via EMM or mobile device management (MDM) policies
Verify that automatic app updates are enabled on corporate Android fleets

Patch Information

Google addressed CVE-2026-14034 in Chrome 150.0.7871.47. Details are provided in the Chrome Desktop Update Announcement and the Chromium Issue Tracker Entry. Apply the corresponding stable channel release across Android endpoints.

Workarounds

Restrict use of WebXR-dependent sites until patched builds are deployed across the fleet
Advise users on Android to avoid untrusted links that request immersive session permissions
Enforce browser update baselines through mobile device management policies to prevent version drift

bash

# Verify Chrome version on a managed Android device via ADB
adb shell dumpsys package com.android.chrome | grep versionName
