This may cause downstream log processing systems to reject or fail to index affected records.\n\nAn attacker can exploit this issue only if both of the following conditions are met:\n\n * The application uses JsonTemplateLayout.\n * The application logs a MapMessage containing an attacker-controlled floating-point value.\n\n\nUsers are advised to upgrade to Apache Log4j JSON Template
