CVE-2026-35394Public exploitNetwork attack vector

Android intent execution via unvalidated URL schemes

Published Apr 6, 2026 · Updated Apr 6, 2026

Improper URL-scheme authorization in Mobile MCP before 0.0.50 allows remote attackers to execute arbitrary Android intents. The mobile_open_url handler passes its URL to adb shell am start with the VIEW action without validating the scheme. Exploitation requires malicious content to influence an AI agent while an Android device is connected; it can invoke USSD, start calls, draft SMS messages, or request content-provider data.
