Descriptions
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.
Se encontró una falla en Keycloak en las solicitudes de autorización push (PAR) de OAuth 2.0. Se descubrió que los parámetros proporcionados por el cliente estaban incluidos en texto plano en la cookie KC_RESTART devuelta por la respuesta HTTP del servidor de autorización a una solicitud de autorización `request_uri`, lo que posiblemente conduzca a una vulnerabilidad de divulgación de información.
