CVE-2026-18010 Overview
CVE-2026-18010 is a user interface (UI) spoofing vulnerability in the Passwords component of Google Chrome. The flaw affects Chrome versions prior to 151.0.7922.72 and stems from an inappropriate implementation in how the browser renders password-related UI elements. A remote attacker can exploit the issue by delivering malicious network traffic to a victim's browser. Chromium engineers rated the security severity as Low. The vulnerability was addressed in the Chrome Stable channel update on the desktop platform.
Critical Impact
Remote attackers can spoof password-related browser UI through crafted network traffic, potentially tricking users into disclosing credentials to attacker-controlled interfaces.
Affected Products
- Google Chrome for Desktop versions prior to 151.0.7922.72
- Chromium-based browsers incorporating the affected Passwords component
- Downstream distributions that had not yet integrated the Chrome 151 stable release

Technical Details for CVE-2026-18010
Vulnerability Analysis
The vulnerability is classified as UI spoofing (User Interface Confusion) within the Chrome Passwords subsystem. Chrome's Passwords feature manages saved credentials, autofill prompts, and password-related warnings shown to users. An inappropriate implementation in this component allows an attacker to influence the rendered UI through malicious network traffic. Users may see password prompts or indicators that do not accurately reflect the true origin or state of the page. This class of flaw undermines the visual trust signals users rely on to distinguish legitimate credential prompts from attacker-crafted content. Google classified the underlying Chromium severity as Low, indicating limited direct security impact absent user interaction.
Root Cause
The root cause is an inappropriate implementation in the Passwords component of Chrome. The component fails to properly constrain how network-supplied content can influence password-related UI surfaces. Full technical details are tracked in the Chromium Issue Tracker Entry.
Attack Vector
Exploitation requires a remote attacker to deliver crafted network traffic to a victim running an unpatched Chrome build. The attacker manipulates the response content or timing to cause Chrome's Passwords UI to render in a misleading way. No verified proof-of-concept code has been published. Refer to the Google Chrome Stable Update advisory for release-level context.
No verified exploitation code is publicly available for CVE-2026-18010.

Detection Methods for CVE-2026-18010
Indicators of Compromise
- No public indicators of compromise have been associated with CVE-2026-18010 at time of publication.
- Absence of the Chrome update to 151.0.7922.72 or later on managed endpoints indicates exposure.
Detection Strategies
- Inventory installed Chrome versions across the fleet and flag any build older than 151.0.7922.72.
- Monitor endpoint browser telemetry for unusual credential-entry patterns following visits to untrusted sites.
- Correlate user reports of unexpected password prompts with recent network destinations to identify potential spoofing attempts.
Monitoring Recommendations
- Track Chrome update compliance through enterprise browser management or endpoint management tooling.
- Ingest browser version data into your SIEM or data lake to alert on stale installations.
- Watch for phishing campaigns that pair credential-harvesting pages with UI manipulation techniques.
How to Mitigate CVE-2026-18010
Immediate Actions Required
- Update Google Chrome to version 151.0.7922.72 or later on all desktop platforms.
- Force-restart Chrome on managed devices to ensure the patched binary is loaded.
- Verify Chromium-derived browsers used in the environment have integrated the corresponding upstream fix.
Patch Information
Google released the fix in the Chrome Stable channel update covered by the Google Chrome Stable Update. Installing Chrome 151.0.7922.72 or later remediates the issue. Enterprises using Chromium-based browsers should confirm their vendor has picked up the upstream commit referenced in the Chromium Issue Tracker Entry.
Workarounds
- No official workaround has been published; applying the vendor patch is the supported remediation path.
- Reinforce user awareness training on validating URL bars and password prompts before entering credentials.
- Restrict browsing to trusted destinations through enterprise web filtering until patch deployment completes.
# Verify installed Chrome version on Linux/macOS endpoints
google-chrome --version
# Expected output: Google Chrome 151.0.7922.72 or later
