Sandbox CSP Blocking Inline Scripts — Any Fix or Workaround?

[magistvupdate_u]

While testing the sandbox environment I noticed repeated CSP blocking issues with inline scripts and styles. It looks similar to the recent sandbox configuration changes discussed here. I also reviewed similar token authentication setups while working on a Firestick integration topic.

If anyone has confirmed whether Authorize. Net adjusted the test endpoint security policy, please share the latest update. Thanks.

I started getting CSP-related issues in the Sandbox and posted about it here: https://community.developer.cybersource.com/t5/Integration-and-Testing/Accept-Hosted-iFrame-Sandbox-...

So we ae dead in the water because we can't change anything about the auth.net form embedded in the iFrame. I also submitted a support ticket. I'm not sure if this is the exact same, but it sounds like it.

Inline script blocking under a strict CSP can definitely be frustrating, especially when you’re testing things in a sandboxed environment. In many cases, the cleanest workaround is refactoring inline scripts into external files and whitelisting them properly, since that keeps security intact and avoids unsafe inline exceptions. Some platforms choose this route to stay compliant while still delivering dynamic features. You see similar approaches on content heavy sites that need to work across many devices and regions. For example  https://emigrantastv.com/ handles streaming and user interactions without relying on risky inline scripts, which helps maintain stability and security. Planning CSP early usually saves a lot of headaches later.
