제목fatbobman mail-mcp-bridge d9e7d9acc2abcf9da8252d76506fc5afbc08d08e Path Traversal
설명The `cleanup_attachments` MCP tool accepts a list of RFC `message_ids` and is intended to remove temporary extraction directories beneath the attachment cache root. However, the implementation only strips angle brackets from each `message_id` before joining it under the base directory. Traversal sequences such as `../mail-mcp-bridge-poc` survive unchanged, so the server resolves a path outside `mail-mcp-attachments` and recursively deletes it with `shutil.rmtree()`. This provides a real arbitrary-directory deletion primitive relative to the temp root used by the service. The related extraction flow in `extract_attachments.py` repeats the same unsafe `message_id`-to-directory join when creating directories.
