| Titel | j3k0 mcp-google-workspace 1.0.0 Arbitrary File Write |
|---|
| Beschreibung | An arbitrary file write vulnerability has been identified in mcp-google-workspace. Gmail attachment retrieval and bulk-save logic accepts caller-controlled local save paths and passes them to fs.writeFileSync after a helper named validateSavePath. The helper resolves the path but does not enforce a safe base directory or approved downloads directory. An attacker able to invoke the affected MCP tool can write decoded attachment content to arbitrary local paths writable by the server process. |
