Gli aggressori stanno gi\u00e0 abusando del difetto in natura per bypassare i controlli di autenticazione.<\/strong><\/p>\n\n<h3 class=\"wp-block-heading\">Un intestazione host manomesso avvelena il percorso<\/h3>\n\n<p class=\"wp-block-paragraph\">Al centro del problema manca la validazione dell&#8217;intestazione HTTP Host. Starlette assembla il <code>request.url<\/code> propriet\u00e0 dall&#8217;intestazione host controllabile e dal percorso di richiesta, quindi ri-parra il risultato. Di conseguenza, <code>request.url.path<\/code> pu\u00f2 divergere dal percorso che il server ASGI utilizza effettivamente per il routing. Se un middleware valuta i diritti di accesso basati su <code>request.url.path<\/code>, valuta un percorso forgiato mentre il percorso autenticamente protetto esegue ancora in background.<\/p><div
