Summary of Changes

Hello @Nirvan-Bobde30, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the security configuration of the application by updating the firebase.json file. The changes involve refining existing security headers and introducing a new one to bolster protection against common web vulnerabilities, ensuring a more secure and robust user experience, especially in contexts involving Shopify integration.

Highlights

• Removed X-Frame-Options: The X-Frame-Options header, previously set to SAMEORIGIN, has been removed from the Firebase hosting configuration.
• Enhanced Content Security Policy: The Content-Security-Policy has been updated to allow scripts from *.firebaseapp.com and to explicitly define frame-ancestors for https://admin.shopify.com and https://*.myshopify.com, improving integration with Shopify.
• Strengthened Strict Transport Security: The strict-transport-security header now includes the preload directive, signaling to browsers that the site should only be accessed using HTTPS.
• Added X-Content-Type-Options: A new X-Content-Type-Options header with the value NoSniff has been added to prevent browsers from MIME-sniffing a response away from the declared content type.

Code Review

This pull request aims to improve security by adding and updating HTTP headers in firebase.json. The changes include adding X-Content-Type-Options, enabling HSTS preloading, and updating the Content-Security-Policy (CSP). While these are positive changes, I've found a critical syntax error in the CSP that could render it ineffective. I've also highlighted a potentially breaking change in the connect-src directive. Additionally, please note that the header configurations are duplicated across the prod, dev, and uat environments, which increases the maintenance effort and risk of inconsistencies. Careful attention is needed when updating these configurations in the future.

There are a couple of issues with the new Content-Security-Policy value:

• Invalid Syntax: The policy string ends with ; *, which is invalid syntax. This will likely cause browsers to reject the entire CSP header, leaving the application unprotected. The trailing ; * should be removed.
• Potentially Breaking connect-src Change: The connect-src directive was changed from the very permissive 'self' * to the very restrictive 'self'. This is a good security practice, but it will break any functionality that relies on making requests to third-party APIs. If such functionality exists, the required domains must be added to the connect-src directive.

Here is a suggested correction for the syntax issue. You may need to further adjust connect-src based on your application's needs.
