Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.

You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.

What is this endpoint?

.well-known/oauth-authorization-server

OAuth 2.0 Authorization Server Metadata

What an attacker could do

Publishes the authorization server's endpoints and capabilities, letting attackers identify supported (and potentially insecure) grant types, token formats, and registration endpoints to target.

How to defend it

This metadata is intentionally public; secure it by advertising only hardened flows, disabling dynamic client registration if unused, and enforcing PKCE and strict redirect validation.
