Unknown · Gemini-Mcp-Tool · CVE-2026-0755
**Name of the Vulnerable Software and Affected Versions**
gemini-mcp-tool (affected versions not specified)
**Description**
The gemini-mcp-tool software contains a critical flaw in the `execAsync` method that allows for unauthenticated remote code execution (RCE). This issue stems from a lack of proper input validation before executing system calls, enabling attackers to inject malicious shell commands. An attacker can reach a network-accessible MCP endpoint and send crafted input to the `execAsync` method, causing the service to execute commands as the gemini-mcp-tool service account. Successful exploitation could lead to full host compromise, including file read/write access, persistence, credential theft, and potential takeover of AI/ML platforms. The root cause is identified as an OS Command Injection (CWE-78) due to insufficient sanitization and lack of parameterized execution. Attackers can leverage shell metacharacters to inject commands.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
