Description

Jellystat is a free and open source Statistics App for Jellyfin. Prior to version 1.1.10, multiple API endpoints in Jellystat build SQL queries by interpolating unsanitized request-body fields directly into raw SQL strings. An authenticated user can inject arbitrary SQL via `POST /api/getUserDetails` and `POST /api/getLibrary`, enabling full read of any table in the database - including `app_config`, which stores the Jellystat admin credentials, the Jellyfin API key, and the Jellyfin host URL. Because the vulnerable call site dispatches via `node-postgres`'s simple query protocol (no parameter array is passed), stacked queries are allowed, which escalates the injection from data disclosure to arbitrary command execution on the PostgreSQL host via `COPY ... TO PROGRAM`. Under the role shipped by the project's `docker-compose.yml` (a PostgreSQL superuser), no additional privileges are required to reach the RCE primitive. Version 1.1.10 contains a fix.
