CVE-2025-11210: Google Chrome Information Disclosure Flaw

CVE-2025-11210 Overview

CVE-2025-11210 is a side-channel information leakage vulnerability in the Tab component of Google Chrome versions prior to 141.0.7390.54. A remote attacker can exploit this weakness by convincing a user to engage in specific user interface gestures on a crafted HTML page. Successful exploitation enables user interface (UI) spoofing, which can mislead users into trusting attacker-controlled content. The Chromium project classified the security severity as Medium. The flaw is tracked under CWE-1300: Improper Protection of Physical Side Channels and affects Chrome on Windows, macOS, and Linux.

Critical Impact
Attackers can spoof browser UI elements to deceive users, enabling credential harvesting and phishing scenarios against any Chrome installation older than 141.0.7390.54.

Affected Products

Google Chrome versions prior to 141.0.7390.54
Chrome on Microsoft Windows
Chrome on Apple macOS and Linux

Technical Details for CVE-2025-11210

Vulnerability Analysis

The vulnerability resides in Chrome's Tab handling logic, where side-channel behavior leaks state information to a crafted HTML page. An attacker who lures a user into performing specific UI interactions can infer or influence tab state to render deceptive interface elements. The result is a UI spoofing condition, allowing malicious pages to imitate trusted browser chrome or overlay convincing prompts. This class of weakness maps to [CWE-1300], which covers improper protection of side channels that expose sensitive state.

Root Cause

The root cause is insufficient isolation of observable state within the Tab component. Timing or rendering signals emitted during user gestures can be measured by a hostile page. Chromium engineers addressed the defect in the Stable channel update for desktop, published on the Google Chrome Releases blog. Additional engineering context is tracked in the Chromium Issue Tracker Entry.

Attack Vector

Exploitation requires network delivery of a crafted HTML page and active user interaction, such as clicking, dragging, or hovering across specific interface elements. Once the victim performs the required gesture, the attacker's page correlates the side-channel signal with tab state and renders spoofed UI. Neither special privileges nor prior authentication are required. The vulnerability does not permit code execution or persistent compromise on its own, but it materially strengthens phishing and social engineering workflows.

No verified public proof-of-concept code is available. See the Chromium Issue Tracker Entry for engineering details.

Detection Methods for CVE-2025-11210

Indicators of Compromise

Chrome browser processes reporting a version string below 141.0.7390.54 in endpoint inventory data.
User reports of unexpected browser prompts, duplicated tab bars, or credential requests appearing over web content.
Outbound HTTP requests to newly registered domains hosting HTML pages that request unusual click, drag, or hover sequences.

Detection Strategies

Query endpoint telemetry to enumerate installed Chrome versions and flag hosts running builds earlier than 141.0.7390.54.
Correlate web proxy logs with threat intelligence to identify visits to known phishing infrastructure that leverages UI spoofing.
Monitor for browser child processes rendering full-viewport overlays combined with high-frequency user input events.

Monitoring Recommendations

Ingest browser version telemetry into the SIEM and alert on hosts that miss the Chrome auto-update cycle.
Track user-reported phishing submissions to detect campaigns that exploit UI spoofing primitives.
Baseline typical user-gesture patterns and alert on pages that programmatically prompt unusual interaction sequences.

How to Mitigate CVE-2025-11210

Immediate Actions Required

Update Google Chrome to version 141.0.7390.54 or later on all Windows, macOS, and Linux endpoints.
Verify that Chrome auto-update is enabled and functioning through enterprise policy.
Communicate phishing awareness guidance emphasizing verification of address bar and prompt origins.

Patch Information

Google released the fix in the Chrome Stable channel. Full details are published in the Google Chrome Stable Update advisory. Enterprises using managed Chrome deployments should push the update through Google Admin console, Group Policy, or their existing software distribution platform. Chromium-based browsers that rebase on the affected code should confirm they have merged the corresponding upstream fix.

Workarounds

Restrict browsing to trusted domains through enterprise proxy allowlists until the patch is deployed.
Disable execution of untrusted JavaScript on high-risk endpoints using Chrome enterprise policies such as DefaultJavaScriptSetting.
Train users to close tabs and re-authenticate via bookmarks when browser UI behaves unexpectedly.
