CVE-2026-13932 Overview
CVE-2026-13932 is an inappropriate implementation vulnerability in the Sharing component of Google Chrome on Android prior to version 150.0.7871.47. A remote attacker who has already compromised the renderer process can leak cross-origin data by serving a crafted HTML page to the victim. Google Chromium classifies this issue as Medium severity, and it is tracked under [CWE-284: Improper Access Control].
The flaw undermines the browser's same-origin policy, a core web security boundary that isolates content served from different origins. Successful exploitation requires user interaction and a prior renderer compromise, which limits standalone impact but makes the bug useful as part of an exploit chain.
Critical Impact
Cross-origin data leakage via a crafted HTML page on Android Chrome versions prior to 150.0.7871.47 after a renderer process is compromised.
Affected Products
- Google Chrome on Android prior to 150.0.7871.47
- Google Android platform builds shipping the affected Chrome versions
- Chromium-based components relying on the vulnerable Sharing implementation

Technical Details for CVE-2026-13932
Vulnerability Analysis
The vulnerability resides in the Sharing feature of Google Chrome on Android. Sharing coordinates data flow between the browser and other applications or origins when users invoke share actions. An inappropriate implementation in this component allows a compromised renderer to access data belonging to a different web origin.
Because the attack requires prior renderer compromise, it is typically chained after a separate memory corruption or logic bug that gives the attacker code execution inside the sandboxed renderer. From that position, the attacker uses the flawed Sharing pathway to read cross-origin content that should be inaccessible under the same-origin policy.
The issue is classified under [CWE-284: Improper Access Control]. Only confidentiality is impacted; integrity and availability are not affected. User interaction is required, meaning the victim must load or interact with the crafted HTML page.
Root Cause
The root cause is improper access control in the Sharing implementation. The component fails to enforce origin boundaries when handling shared data, allowing a compromised renderer to observe values that originate from a different origin. Details are tracked in the Chromium Issue Tracker Entry.
Attack Vector
An attacker delivers a crafted HTML page to a victim running an affected version of Chrome on Android. The page triggers the flawed Sharing pathway from within a renderer the attacker already controls. The renderer then reads cross-origin data that would normally be blocked by browser security boundaries. No elevated privileges are needed on the target device, but user interaction with the crafted page is required.
No public proof-of-concept or exploit code has been published for CVE-2026-13932. See the Google Chrome Stable Update advisory for vendor context.
Detection Methods for CVE-2026-13932
Indicators of Compromise
- Chrome for Android clients reporting versions below 150.0.7871.47 in telemetry or user-agent strings.
- Unexpected outbound requests from mobile browsers to attacker-controlled domains following visits to untrusted links.
- Renderer crash reports or anomalous WebContents behavior preceding data exfiltration attempts.
Detection Strategies
- Inventory mobile endpoints and enumerate installed Chrome versions to identify unpatched devices.
- Correlate mobile web proxy logs with known malicious infrastructure serving crafted HTML payloads.
- Monitor for renderer-process exploit precursors, since CVE-2026-13932 requires a prior renderer compromise to be useful.
Monitoring Recommendations
- Track Chrome update rollout status across managed Android fleets through mobile device management (MDM) reporting.
- Alert on browser telemetry showing unexpected cross-origin resource access patterns.
- Review threat intelligence feeds for exploit-chain reporting that references Chromium issue 513001690.
How to Mitigate CVE-2026-13932
Immediate Actions Required
- Update Google Chrome on Android to version 150.0.7871.47 or later on all managed devices.
- Enforce automatic Chrome updates through Google Play and enterprise MDM policies.
- Instruct users to avoid untrusted links and unknown web content until patching is confirmed.
Patch Information
Google addressed CVE-2026-13932 in Chrome 150.0.7871.47 for Android. Details are documented in the Google Chrome Stable Update release notes. Verify installed versions through chrome://version or MDM inventory reports.
Workarounds
- No vendor-supplied workaround exists; upgrading to the fixed version is the required remediation.
- Restrict browsing to trusted sites on unpatched devices until updates are deployed.
- Use enterprise browser policies to limit high-risk web content categories where feasible.
# Verify Chrome for Android version via ADB
adb shell dumpsys package com.android.chrome | grep versionName
# Expected output should show 150.0.7871.47 or later
# versionName=150.0.7871.47
