The StatusManagerServlet could be loaded by a web application when a security manager was configured. This servlet would then provide the web application with a list of all deployed applications and a list of the HTTP request lines for all requests currently being processed. This could have exposed sensitive information from other web applications such as session IDs to the web application. Apache Tomcat versions 6.0.0 through 6.0.44, 7.0.0 through 7.0.67, 8.0.0.RC1 through 8.0.30, and 9.0.0.M1 are affected.
