Is this vulnerability remotely exploitable?

It can be, depending on how MCP configuration is exposed. If a remote interface, sync mechanism, or integration allows an attacker to set or modify MCP server commands, they may exploit the issue without local access. In more locked-down setups, exploitation may require local or authenticated access to configuration.

What level of access does an attacker need to exploit this?

An attacker needs the ability to influence MCP server command or argument configuration and to trigger or wait for a connection test. This might be through direct access to the Blinko UI, configuration files, or any automation that populates those settings.

What is the safest general fix pattern?

The safest approach is to avoid executing arbitrary user-specified command lines. Instead, restrict MCP servers to a controlled set of executables with predefined argument templates, use non-shell process creation APIs, and enforce strict validation on any remaining configurable parameters.
