CVE-2026-35394 Details
Description
Mobile Next is an MCP server for mobile development and automation. Prior to 0.0.50, the mobile_open_url tool in mobile-mcp passes user-supplied URLs directly to Android's intent system without any scheme validation, allowing execution of arbitrary Android intents, including USSD codes, phone calls, SMS messages, and content provider access. This vulnerability is fixed in 0.0.50.
A vulnerability in Mobile Next's MCP server for mobile development and automation, prior to version 0.0.50, allows the 'mobile_open_url' tool to pass user-supplied URLs directly to Android's intent system without validating the URL scheme. This oversight enables the execution of arbitrary Android intents, such as USSD codes, phone calls, SMS messages, and access to content providers. The issue arises because the vulnerable code transmits URLs to the intent system without proper checks, leaving room for malicious schemes to be executed on connected mobile devices.
Users are advised to upgrade to version 0.0.50 or later, which restricts the 'mobile_open_url' tool to 'http://' and 'https://' schemes by default. Those who need to use other URL schemes can enable them by setting the 'MOBILEMCP_ALLOW_UNSAFE_URLS' environment variable to '1'.
