Descriptions
A flaw was found in the offline_access scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user.
Se encontró una falla en el alcance offline_access en Keycloak. Este problema afectaría más a los usuarios de ordenadores compartidos (especialmente si las cookies no se borran), debido a la falta de validación de la sesión root y a la reutilización de los identificadores de sesión en las sesiones de autenticación de usuario y root. Esto permite a un atacante resolver una sesión de usuario adjunta a un usuario previamente autenticado; al utilizar el token de actualización, se les emitirá un token para el usuario original.
