The festivaltts4r gem for Ruby allows remote attackers to execute arbitrary commands via shell metacharacters in a string to the (1) to_speech or (2) to_mp3 method in lib/festivaltts4r/festival4r.rb.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
