Original Bulletin:

- --------------------------BEGIN INCLUDED TEXT--------------------

CVE-2018-8014 Insecure defaults for CORS filter

Severity: Low

Vendor: The Apache Software Foundation

Versions Affected:
Apache Tomcat 9.0.0.M1 to 9.0.8
Apache Tomcat 8.5.0 to 8.5.31
Apache Tomcat 8.0.0.RC1 to 8.0.52
Apache Tomcat 7.0.41 to 7.0.88

The defaults settings for the CORS filter are insecure and enable
'supportsCredentials' for all origins.
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.

Users of the affected versions should apply one of the following
- - 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
