CVE-2026-13936 Overview
CVE-2026-13936 is an information disclosure vulnerability in the Passwords component of Google Chrome on Android. The flaw affects Chrome versions prior to 150.0.7871.47 and stems from an inappropriate implementation categorized under [CWE-284] Improper Access Control. A remote attacker can craft a malicious HTML page that, when rendered by a vulnerable Chrome instance, leaks potentially sensitive information from process memory. Exploitation requires user interaction, typically by convincing a target to visit the attacker-controlled page. Google classifies the Chromium security severity as Medium.
Critical Impact
A crafted HTML page can extract sensitive data from Chrome's process memory on Android devices, potentially exposing credentials handled by the Passwords component.
Affected Products
- Google Chrome on Android prior to 150.0.7871.47
- Google Android (host platform running vulnerable Chrome builds)
- Chromium-based components inheriting the Passwords implementation

Technical Details for CVE-2026-13936
Vulnerability Analysis
The vulnerability resides in the Passwords subsystem of Google Chrome on Android. An inappropriate implementation permits a remote attacker to observe or infer contents of process memory that should remain isolated from web content. The classification [CWE-284] indicates that the access control boundary between untrusted web content and privileged password-handling state is not correctly enforced.
The attack requires the victim to load a crafted HTML page in an unpatched Chrome build. No authentication or elevated privileges are required on the target device. The confidentiality impact is significant because the Passwords component handles credentials, autofill data, and related secrets. Integrity and availability are not affected, and the flaw does not directly grant code execution.
Exploit maturity is limited at disclosure. No public proof-of-concept, exploit database entry, or CISA KEV listing exists for this CVE. The EPSS probability sits at approximately 0.288 percent.
Root Cause
The root cause is improper access control within the Passwords implementation, allowing web-origin content to reach memory regions that should be inaccessible to renderer-reachable code paths. See the Chromium Issue Tracker #513044658 for restricted technical details.
Attack Vector
The attack vector is network-based via a crafted HTML page. An attacker hosts the malicious document on an attacker-controlled site or injects it into a compromised page. When a user with a vulnerable Chrome build on Android navigates to the page, the crafted content triggers the flawed Passwords code path and leaks memory contents back to attacker-observable channels.
No verified public exploit code is available. Refer to the Google Chrome Releases advisory for the vendor announcement.
Detection Methods for CVE-2026-13936
Indicators of Compromise
- Chrome on Android reporting a version string earlier than 150.0.7871.47 in chrome://version or enterprise inventory.
- Outbound connections from mobile browsers to unfamiliar domains immediately after loading unsolicited links from email, SMS, or messaging apps.
- Anomalous credential reuse or password-manager autofill events that do not correlate to legitimate user activity.
Detection Strategies
- Inventory managed Android endpoints and flag Chrome installations below 150.0.7871.47 using MDM or UEM telemetry.
- Correlate web proxy or DNS logs against threat intelligence feeds to identify visits to pages hosting Chrome renderer exploits.
- Monitor for repeated navigation to newly registered domains that deliver obfuscated HTML or JavaScript payloads to mobile user agents.
Monitoring Recommendations
- Enable centralized reporting of Chrome browser versions across the mobile fleet and alert on drift from the current stable channel.
- Track credential-reset events and password-manager sync anomalies that may indicate downstream misuse of leaked secrets.
- Retain mobile browser and network telemetry for at least 90 days to support retrospective hunts once additional indicators emerge.
How to Mitigate CVE-2026-13936
Immediate Actions Required
- Update Google Chrome on Android to version 150.0.7871.47 or later through the Google Play Store.
- Push the update via mobile device management for managed fleets and verify installation on enrolled devices.
- Advise users to avoid clicking untrusted links on Android devices until patch coverage is confirmed.
Patch Information
Google addressed the vulnerability in Chrome 150.0.7871.47 for Android. Details are provided in the Google Chrome Stable Channel Update. Restricted technical context is tracked in Chromium Issue #513044658.
Workarounds
- Restrict browsing on unpatched Android devices to trusted, allowlisted domains until the update is deployed.
- Disable Chrome password autofill and saved-password features on unpatched devices to reduce exposure of credential material.
- Use enterprise mobility policies to enforce automatic Chrome updates and block installation of outdated Chrome builds.
# Configuration example
# Verify Chrome version on a managed Android device via adb
adb shell dumpsys package com.android.chrome | grep versionName
# Force-update Chrome through Google Play (managed configuration)
adb shell am start -a android.intent.action.VIEW \
-d "market://details?id=com.android.chrome"
