In which I survey CSRF countermeasures and existing Go libraries and propose we add CrossOriginForgeryHandler to net/http to solve this once and for all.
Turns out there is no need for tokens or keys in 2025! Browsers just send a This-Is-CSRF header now. (Sort of.)

I talk about this on the pod all the time, but CSRF is dead simple. You just need to know the conditions.
I'm not gonna recite them again here, but today a new condition came up:
No Content-Type header -> no CSRF restrictions
Same-site: None
POST
= CSRF
The research:

Hi. For anyone seeing this, this is fake (or likely misiattributed). The survey in question didn't ask for authentication. On top of that, clicking a link can't steal your auth token because that would be a MAJOR CSRF exploit. Also, here's the survey site's SSL cert info.

I'm looking into github.com/gorilla/csrf to figure out if we could bring CSRF protection to the standard library.
I am 90% sure the secret key is useless: it signs a random token with no metadata, and the attacker can just get and reuse a valid signed token.
Am I missing something?

I implemented the proposed CSRF handler, if anyone wants to test it, or wants to migrate before it makes its way into the standard library.
There are are no tokens or cookies, so migrating should be easy, but note that it applies strict same-origin checks.
Feedback welcome!
