Summary

Office-PowerPoint-MCP-Server through version 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.

Risk Assessment

The risk includes the possibility of overwriting critical server files, leading to data corruption, system integrity compromise, or unauthorized access to sensitive files outside the working directory.

Recommendation

It is recommended to update Office-PowerPoint-MCP-Server to a version newer than 2.0.7 and implement path validation to block access to files outside the allowed directory. Also, restrict server write permissions to the minimum scope.
