You can update the user's attribute in the session by admin API.

            "value2"
        ],

        ]
    }
}

Notice the Body parameter using a UserRepresentation object. When you go to that link https://www.keycloak.org/docs-api/18.0/rest-api/#_userrepresentation you can see that it contains an optional field for attributes:
