CVE-2026-81562Public exploitHinoki check available

Local host command execution via ampersand bypass

Published Aug 27, 2026 · Updated Aug 27, 2026

OS command injection in Alex Gladkov claude-in-mobile 3.10.2 allows local users to execute commands through the system_shell tool. The ADB client's exec method interpolates caller-controlled command text into an execSync string, while its denylist fails to reject a standalone ampersand. Any MCP caller able to invoke system_shell can run commands with the MCP server process owner's privileges, even without an Android device.
