Fix some issue with insecure browsers.

[comfyanonymous]

If you are on a recent chromium or chrome based browser this doesn't affect you.

This is to give time for the lazy firefox devs to implement PNA.

📝 Walkthrough

Walkthrough

The change adds an early security check in the origin-only middleware function. When a request includes a Sec-Fetch-Site header with the value cross-site, the middleware now immediately returns an HTTP 403 response. This header-based validation occurs before the existing origin and host matching logic, providing an additional rejection pathway compared to the previous implementation.

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Title check	❓ Inconclusive	The title is vague and uses non-descriptive terms like 'some issue' that don't convey meaningful information about what the change actually does.	Clarify the title to specifically mention the Sec-Fetch-Site header check or the security mechanism being implemented.
