Tl;dr: If you are a developer considering adding World ID to your project. Wait.

If you see an app using World ID. Be safe.

The OAuth Best Security Current Practices have not been followed. Combined with the following point, applications using World ID may be vulnerable to attacks.

The implementation is not compliant with the OpenID Connect specification. Times are in milliseconds instead of seconds, requests can be made without required parameters. Update Aug 9, these have been addressed.

The user’s privacy is being violated. The authorization page presents no information on what the application is requesting, nor on what worldcoin.org is releasing. There are no application terms of service and privacy policy links.
