It is expected that users of the CORS filter will have configured it appropriately for their environment rather than using it in the default configuration. Therefore, it is expected that most users will not be impacted by this issue. Mitigation: Users of the affected versions should apply one of the following mitigations. - Configure the filter appropriately for your environment Secure defaults will be provided in the following versions: - Apache Tomcat 9.0.9 or later when released - Apache Tomcat 8.5.32 or later when released - Apache Tomcat 8.0.53 or later when released - Apache Tomcat 7.0.89 or later when released History: 2018-05-15 Original advisory References:  http://tomcat.apache.org/security-9.html  http://tomcat.apache.org/security-8.html  http://tomcat.apache.org/security-7.html
