Keycloak: exposure of sensitive information in pushed authorization requests (par) kc_restart cookie

A flaw was found in Keycloak in OAuth 2.0 Pushed Authorization Requests (PAR). Client-provided parameters were found to be included in plain text in the KC_RESTART cookie returned by the authorization server's HTTP response to a `request_uri` authorization request, possibly leading to an information disclosure vulnerability.
