In affected versions the `/api/Image/WithPath` endpoint is accessible without authentication and is supposed to return default server images. The endpoint accepts the parameter `serverImagePath`, which is not sanitized in any way before being passed to `System.IO.File.OpenRead`, which results in an arbitrary file read. This issue may lead to an arbitrary file read which is exacerbated in the windows installer which installs the ShokoServer as administrator. Any unauthenticated attacker may be able to access sensitive information and read files stored on the server. The `/api/Image/WithPath` endpoint has been removed in commit `6c57ba0f0` which will be included in subsequent releases. Users should limit access to the `/api/Image/WithPath` endpoint or manually patch their installations until a patched release is made. This issue was discovered by the GitHub Security lab and is also indexed as GHSL-2023-191."}, {"lang": "es", "value": "ShokoServer es un servidor de medios que se especializa en organizar anime.

El endpoint acepta el par\u00e1metro `serverImagePath`, que no se sanitiza de ninguna manera antes de pasarse a `System.IO.File.OpenRead`, lo que da como resultado una lectura de archivo arbitraria.
