Closes #40163
Added a check to ensure that the
client_id
matches theapp_id
contained in the response from the custom Facebook/debug_token
endpoint. To invoke the debug endpoint, an "app access token" is required, which can either be in the formclient_id|client_secret
or obtained via the client credentials grant. However, I noticed that with the default settings, the "app access token" is returned from client credential grant asclient_id|client_secret
in plain so I skipped this additional step. Since we don't have automated tests, I also added the option to disable this verification (enabled by default).
