Improper Input Validation vulnerability in Apache Tomcat.Tomcat from11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTPtrailer headers. A speciallycrafted, invalid trailer header could cause Tomcat to treat a singlerequest as multiple requests leading to the possibility of requestsmuggling when behind a reverse proxy.Older, EOL versions may also be affected.Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue.
