Description Andrej Nemec 2016-04-15 04:21:34 EDT 
Dominic Cleal of Red Hat reports:

A provisioning template containing <%= inspect %> will expose sensitive information about the Rails controller and application when rendered when using Safemode rendering (default).

Safemode is initialised with a "delegate" object that is typically the Rails controller. When inspect is called on it, all information about the Rails app is exposed, including routes, secret tokens, caches and so on.
