CVE-2026-10510 Overview
CVE-2026-10510 is a Cross-Site Scripting (XSS) vulnerability in the GeniexWebView component of the Transsion AI Assistant Lifestyle Android application (com.transsion.aiassistantlifestyle). All versions of the application on Android are affected. A remote attacker can execute arbitrary JavaScript in the WebView context by supplying a crafted web_action_data URL parameter. The flaw is classified under CWE-79 and requires user interaction, typically by inducing a victim to open a malicious link handled by the application.
Critical Impact
Arbitrary JavaScript execution inside the application's WebView context, enabling theft of in-app data, session abuse, and abuse of any JavaScript bridges exposed to the WebView.
Affected Products
- Transsion AI Assistant Lifestyle Android application (com.transsion.aiassistantlifestyle) — all versions
- GeniexWebView component within the affected application
- Android devices with the vulnerable application installed (Tecno, Infinix, itel handsets ship Transsion software)

Technical Details for CVE-2026-10510
Vulnerability Analysis
The vulnerability resides in the GeniexWebView component, an Android WebView wrapper used by the Transsion AI Assistant Lifestyle application. The component accepts a web_action_data URL parameter and passes its value into the WebView without proper sanitization or output encoding. An attacker who controls the value of web_action_data can inject HTML or JavaScript that the WebView renders and executes within the application's origin context.
Because the executed script runs inside the application's WebView, it can access any DOM state, cookies, or local storage scoped to that view. If the application exposes Java-to-JavaScript bridges via addJavascriptInterface, injected code may also invoke privileged native methods. User interaction is required, consistent with typical reflected XSS chains delivered through a crafted deep link, intent, or external URL.
Root Cause
The root cause is missing input validation and output encoding on data flowing from an untrusted URL parameter (web_action_data) into HTML or JavaScript executed by GeniexWebView. This is a classic [CWE-79] failure where attacker-controlled input is reflected into a rendering context without contextual escaping.
Attack Vector
Exploitation occurs over the network and requires the victim to interact with a crafted link, intent, or page that triggers the vulnerable WebView with a malicious web_action_data parameter. Once loaded, the injected JavaScript executes in the WebView origin and may exfiltrate data, manipulate displayed content, or pivot through exposed JavaScript bridges. No code samples have been verified or published; see the Tecno Security Updates advisory for vendor technical detail.
Detection Methods for CVE-2026-10510
Indicators of Compromise
- Inbound deep links or intents targeting com.transsion.aiassistantlifestyle that contain a web_action_data parameter with HTML tags, javascript: URIs, or encoded script payloads.
- Outbound HTTP requests from the application to attacker-controlled domains following user interaction with a third-party link.
- Unexpected JavaScript bridge calls or anomalous data access within WebView session logs.
Detection Strategies
- Inspect mobile proxy and DNS telemetry for URLs containing web_action_data= with suspicious characters such as <, >, %3C, or javascript:.
- Use mobile threat defense tooling to flag the vulnerable package com.transsion.aiassistantlifestyle until a patched version is confirmed installed.
- Apply static and dynamic analysis to in-scope Android builds to identify WebView sinks that consume web_action_data without sanitization.
Monitoring Recommendations
- Monitor enterprise MDM inventories for the presence and version of com.transsion.aiassistantlifestyle on managed Android devices.
- Alert on phishing campaigns delivering links that target Transsion AI Assistant Lifestyle URI handlers.
- Track vendor advisories at Tecno Security Updates for patched build identifiers and roll-out status.
How to Mitigate CVE-2026-10510
Immediate Actions Required
- Update the Transsion AI Assistant Lifestyle application to the latest version once a fixed release is published by the vendor.
- Restrict or remove the application on managed devices that handle sensitive corporate data until a fix is verified.
- Educate users to avoid opening untrusted links that target the application's URI schemes or deep links.
Patch Information
At publication, no specific fixed version has been listed in the NVD record. Refer to the vendor advisory at Tecno Security Updates for patch availability, affected builds, and remediation status.
Workarounds
- Use Android MDM policy to block the package com.transsion.aiassistantlifestyle from launching arbitrary deep links from untrusted sources.
- Disable or sandbox the AI Assistant Lifestyle application on devices used for high-sensitivity workloads.
- Apply network-level filtering of URLs containing web_action_data parameters with script-like payloads.
# Example: query installed package version on a managed Android device via adb
adb shell dumpsys package com.transsion.aiassistantlifestyle | grep versionName
