      "value": "MaxKB is an open-source AI assistant for enterprise. In versions 2.0.0 through 2.10.4-lts, UpdateStoreTool.update_tool passes caller-supplied download_url and download_callback_url values to requests.get without equivalent trusted-host and redirect validation, allowing an authenticated workspace user to make the server request internal, loopback, link-local, or cloud metadata URLs. A fix is present on the v2 branch but has not yet been included in a published release."

En las versiones 2.0.0 hasta la 2.10.4-lts, UpdateStoreTool.update_tool pasa valores de download_url y download_callback_url suministrados por el llamador a requests.get sin una validación equivalente de host de confianza y redirección, permitiendo que un usuario autenticado del espacio de trabajo haga que el servidor solicite URLs internas, de bucle invertido, de enlace local o de metadatos en la nube. Una solución está presente en la rama v2 pero aún no ha sido incluida en una versión publicada."
