Hello all,
A new CVE for Tomcat. While its severity is graded as "Low" please act on
it by removing the examples web application that comes with a typical
Tomcat installation (i.e: $TOMCAT_HOME/webapps/examples) if you haven't
already done so. We encourage everyone to remove all unused
web applications that come with a default Tomcat installation for this
reason.
