Hi,

Isn't there a risk of an attacker logging a user out of a third-party
(victim) site just by loading that logout_url? At a minimum the RP should
check the request's origin or referrer but AFAIK this wouldn't be reliable
with such cross-origin requests (at least for older browsers not sending an
Origin header), but maybe the OP could compute some value based on a shared
secret, or use a signed JWT, and pass it as a query string parameter to
"authenticate" the request?
