In agent/Core/SpawningKit/Spawner.h in Phusion Passenger 5.1.10 (fixed in
Passenger Open Source 5.1.11 and Passenger Enterprise 5.1.10), if Passenger
is running as root, it is possible to list the contents of arbitrary files
on a system by symlinking a file named REVISION from the application root
folder to a file of choice and querying passenger-status --show=xml.
