      "value": "zrok is software for sharing web services, files, and network resources. Prior to 2.0.3, zrok's Python SDK ProxyShare Flask proxy route accepts an absolute URL in the request path and passes it to urllib.parse.urljoin, allowing the requested path to replace the configured target host and causing requests.request to return a server-side response from an attacker-chosen URL. This issue is fixed in version 2.0.3."

Antes de la versión 2.0.3, la ruta de proxy ProxyShare Flask del SDK de Python de zrok acepta una URL absoluta en la ruta de la solicitud y la pasa a urllib.parse.urljoin, permitiendo que la ruta solicitada reemplace el host de destino configurado y haciendo que requests.request devuelva una respuesta del lado del servidor desde una URL elegida por el atacante.
