While investigating bug 60718, it was noticed that some calls to application listeners did not use the appropriate facade object. When running an untrusted application under a SecurityManager, it was therefore possible for that untrusted application to retain a reference to the request or response object and thereby access and/or modify information associated with another web application. Apache Tomcat versions 7.0.0 through 7.0.75, 8.0.0.RC1 through 8.0.41, 8.5.0 through 8.5.11, and 9.0.0.M1 through 9.0.0.M17 are affected.
