    "summary": "## Summary An authenticated nginx-ui user can call `POST /api/restore`, upload a forged encrypted backup, restore `app.ini`, set nginx command settings such as `TestConfigCmd`, and then trigger command execution with `POST /api/nginx/test`. This was validated on nginx-ui `2.3.11 2(523) 6c86e5a5` in the local Docker container `uozi/nginx-ui:latest`. ## Impact An authenticated user can overwrite nginx-ui application configuration and database state through restore, including protected settings that are normally not writable through the settings API. By setting nginx command fields in the restored `app.ini`, the attacker can execute commands in the nginx-ui runtime context. This affects confidentiality, integrity, and availability because the attacker can read or replace secrets, change node/JWT secrets, corrupt application state, and execute arbitrary commands. ## Affected Version / Environment - Version: `nginx-ui 2.3.11 2(523) 6c86e5a5` - Deployment: local Docker, `uozi/nginx-ui:latest` - Base URL used in validation: `http://127.0.0.1:8080` ## Root Cause `/api/restore` is reachable through normal authenticated-user authorization. The restore handler accepts attacker-supplied backup key material, validates the manifest with a key derived from that supplied AES key, decrypts attacker-controlled backup contents, and copies restored `app.ini` into the live nginx-ui config path. Relevant code paths: - `api/backup/router.go`: `POST /api/restore` - `api/backup/restore.go`: accepts `",
