Hi all, We are currently implementing the token revocation endpoint (RFC 7009) on our authorization server and do not understand why it requires client authentication. When a party (a valid client or not) gets hold of a valid access token in whatever way, the least damaging it could do with it, is to revoke it. The current spec allows an attacker to misuse this token for access to the resource server, but forbids it to revoke it. This seems strange to me.
Section 5 of RFC 7009 does not help in this either. It starts to explain that this authentication is needed to prevent malicious clients from guessing tokens, but ends with the fact that if this were possible, much worse damage could be done by using the guessed token on the resource server. We plan to skip the authentication all together and simply revoke any valid token presented. How would you recommend we deal with this?
