CVE-2026-14096 Overview
CVE-2026-14096 is an information disclosure vulnerability in the Input component of Google Chrome on Android. Versions prior to 150.0.7871.47 contain an inappropriate implementation that allows a remote attacker who has already compromised the renderer process to leak cross-origin data through a crafted HTML page. The flaw is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor and requires user interaction to trigger. Google assigned this issue a Chromium security severity of Low, while NVD scored it at 6.5 (Medium).
Critical Impact
An attacker controlling a compromised renderer process can exfiltrate cross-origin data, bypassing the Same-Origin Policy that isolates content between web origins.
Affected Products
- Google Chrome for Android versions prior to 150.0.7871.47
- Google Android devices running vulnerable Chrome builds
- Chromium-based Android browsers sharing the affected Input component

Technical Details for CVE-2026-14096
Vulnerability Analysis
The vulnerability resides in Chrome's Input handling code on Android. An inappropriate implementation permits data flow across origin boundaries when the renderer process is already under attacker control. Cross-origin data that should remain isolated by the browser's site isolation and Same-Origin Policy becomes reachable to a crafted HTML page.
Exploitation is a two-stage operation. First, the attacker must compromise the renderer process through a separate bug or exploit chain. Second, the attacker uses the Input flaw to read data belonging to other origins loaded in the browser. Because the initial renderer compromise is a prerequisite, the vulnerability functions as a sandbox-adjacent leak primitive rather than a standalone remote exploit.
Root Cause
The root cause is an implementation defect in the Input subsystem that fails to enforce origin boundaries under adversarial renderer conditions. The code path processes input-related data without applying the checks required to keep cross-origin content isolated. This aligns with [CWE-200] information exposure, where a trust boundary is not correctly enforced during data handling.
Attack Vector
The attack vector is network-based and requires user interaction. A victim must visit or interact with a crafted HTML page delivered by the attacker. Attack complexity is low and no privileges are required. The confidentiality impact is high, while integrity and availability are not affected. Because the attacker must first compromise the renderer, real-world exploitation typically appears as part of a multi-stage browser exploit chain.
No public proof-of-concept, exploit code, or exploit database entry is available for CVE-2026-14096. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS probability sits at 0.229% with a percentile of 13.6, indicating a low predicted likelihood of near-term exploitation.
Detection Methods for CVE-2026-14096
Indicators of Compromise
- Chrome for Android clients reporting version strings earlier than 150.0.7871.47 in telemetry or User-Agent headers.
- Outbound traffic from mobile browsers to attacker-controlled domains hosting HTML pages with unusual cross-origin input handling patterns.
- Anomalous cross-origin data references in browser crash reports or renderer process logs collected by mobile device management.
Detection Strategies
- Inventory Chrome for Android versions across the mobile fleet and flag any device below 150.0.7871.47.
- Correlate mobile browser telemetry with threat intelligence feeds referencing Chromium issue 513310821 or the associated Google advisory.
- Monitor for renderer process crashes on Android endpoints, which often precede or accompany chained browser exploits.
Monitoring Recommendations
- Ingest mobile browser version data into a centralized logging platform and alert on out-of-date Chrome installations.
- Track visits to newly registered or low-reputation domains from managed Android devices via secure web gateway logs.
- Baseline normal renderer crash rates and investigate deviations that could indicate exploitation attempts against Chrome on Android.
How to Mitigate CVE-2026-14096
Immediate Actions Required
- Update Google Chrome on Android to version 150.0.7871.47 or later through the Google Play Store.
- Enforce a minimum Chrome version policy via mobile device management for corporate-managed Android devices.
- Restrict browsing on sensitive Android endpoints until patch deployment is verified across the fleet.
Patch Information
Google addressed CVE-2026-14096 in the Chrome stable channel update referenced in the Google Chrome Stable Update advisory. Additional technical context is available in the Chromium Issue Tracker Entry. Deploy Chrome 150.0.7871.47 or later on all Android devices to remediate the flaw.
Workarounds
- Direct users to an alternative browser on Android until the Chrome update is applied, where feasible.
- Block access to untrusted or newly observed domains at the network perimeter for mobile devices that cannot be immediately updated.
- Educate users to avoid clicking links from unsolicited messages, since exploitation requires user interaction with a crafted page.
