org.apache.tomcat:catalina is a Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Authentication Bypass. By default, Tomcat automatically deploys any directories placed in ahost's appBase. This behaviour is controlled by the autoDeploy attributeofwhich defaults to true. Depending on circumstances, files normally protected by one or more security constraints may be deployed without those security constraints, making them accessible without authentication.
