MCP Server Kubernetes is an MCP Server that can connect to a Kubernetes cluster and manage it. A command injection vulnerability exists in the mcp-server-kubernetes MCP Server. The vulnerability is caused by the unsanitized use of input parameters within a call to child_process.execSync, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges. This vulnerability is fixed in 2.5.0.

serverless MCP Server vulnerable to Command Injection in list-projects tool

CVE-2025-69256 [HIGH] CWE-77 serverless MCP Server vulnerable to Command Injection in list-projects tool
serverless MCP Server vulnerable to Command Injection in list-projects tool
### Summary
A command injection vulnerability exists in the Serverless Framework's built-in MCP server package (@serverless/mcp). This vulnerability only affects users of the experimental MCP server feature (serverless mcp), which represents less than 0.1% of Serverless Framework users. The core Serverless Framework CLI and deployment functionality are not affected.
The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.exec`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges.
The server constructs and executes shell commands using unvalidated user input directl

mcp-kubernetes-server has an OS Command Injection vulnerability
osv·2025-09-15·CVSS 7.5
CVE-2025-59377 [HIGH] mcp-kubernetes-server has an OS Command Injection vulnerability
mcp-kubernetes-server has an OS Command Injection vulnerability
`feiskyer/mcp-kubernetes-server` through **0.1.11** allows **OS command injection** via the `/mcp/kubectl` endpoint. The handler constructs a shell command with user-supplied arguments and executes it with `subprocess` using `shell=True`, enabling injection through shell metacharacters (e.g., `;`, `&&`, `$()`), even when the server is running in **read-only** mode.
A remote, unauthenticated attacker can execute arbitrary OS commands on the host, resulting in full compromise of confidentiality, integrity, and availability.
This issue is **distinct from** `mcp-server-kubernetes` and from **CVE-2025-53355**.

MCP Server Kubernetes vulnerable to command injection in several tools
### Summary
A command injection vulnerability exists in the `mcp-server-kubernetes` MCP Server. The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.execSync`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges.
The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.).

The MCP Server exposes tools (`kubectl_scale`, `kubectl_patch` , `explain_resource`, etc) to perform several kubernetes operations. An MCP Cl
