Markdownify is a Model Context Protocol server for converting almost anything to Markdown. Versions below 0.0.2 contain a command injection vulnerability, 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 directly within command-line strings. This introduces the possibility of shell metacharacter injection (|, >, &&, etc.). This issue is fixed in version 0.0.2.

 https://cve.radiocsirt.org/vuln/ghsa-45qj-4xq3-3c45 GHSA-45qj-4xq3-3c45 — mcp-markdownify-server vulnerable to command injection in pptx-to-markdown tool 2026-10-06T15:09:56.963765+00:00

Affected: npm: mcp-markdownify-server

### Summary

A command injection vulnerability exists in the `mcp-markdownify-server` MCP Server. 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 directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.).

### Details

The MCP Server exposes tools to perform several file operations. An MCP Client can be instructed to execute additional actions for example via indirect prompt injection when asked to read an `md` file. Below some example of vulnerable code and different ways to test this vulnerability including a real example of indirect prompt injection that can lead to arbitrary command injection.

### Vulnerable code

The following snippet illustrates the vulnerable code pattern used in the MCP Server’s tooling.
