| 描述 | # Directory Traversal via task_id Leading to Arbitrary File Overwrite
## Vulnerability Details
- Affected Endpoint `POST /api/upload`
- https://github.com/MigoXLab/LMeterX/blob/main/backend/service/upload_service.py#L100
- https://github.com/MigoXLab/LMeterX/blob/main/backend/service/upload_service.py#L160
A directory traversal vulnerability exists in the file upload functionality, where the `task_id` parameter is used to determine the storage path. By supplying crafted values such as `../`, an attacker can escape the intended `upload_files` directory and write files to arbitrary locations on the server.
## PoC
```bash
curl -X POST "http://localhost:5001/api/upload?task_id=../zznq" \
-F "file=@./pocs/zznq.crt"
```
