# CVE-2025-71427

> 7.6 HIGH · 🧪 PoC

## Beschreibung

Office-PowerPoint-MCP-Server through 2.0.7 contains a path traversal vulnerability that allows MCP callers to write and read files outside the working directory by supplying absolute paths or ../ sequences. Attackers can steer an AI agent via prompt injection to abuse save_presentation, open_presentation, or manage_image output_path to overwrite any server-writable file or load external files.
