gemini-mcp-tool execAsync Command Injection Remote Code Execution Vulnerability (CVE-2026-0755)

This vulnerability allows remote attackers to execute arbitrary code on affected installations of gemini-mcp-tool.

Authentication is not required to exploit this vulnerability.

The specific flaw exists within the implementation of the execAsync method.

The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call.

An attacker can leverage this vulnerability to execute code in the context of the service account.

Currently given the nature of the vulnerability, the only salient mitigation strategy is to restrict interaction with the product.
